As far as I am aware, you dont. I have never heard of or seen a complete list of their products, and given that the majority of their work was one-offs for museums etc, some of which were duplicated, or modified for sales to "us", it is unlikely that such a list exists.
But, from memory (and mine may well be faulty) they did do Duchess in 5" gauge. If you even have a complete set of the drawings for it, you are doing well, as few of their drawings still exist.
Parts? If you happen to find a complete set of their castings for one of their locos, make sure you do the lottery as you will surely be on a winning streak!
I have a couple of Clarkson catalouges at home, I will have a look for you. As Alan says you will be doing well to find any Clarkson material these days. The rights where aquired by a guy who has done nothing with them and doesnt seem to want to do so.
Clarksons did supply drawings & castings for a 3.1/2 G Duchess in 1975.Castings would be impossible to find now.As you may see from my previous posts,I`m building a Clarksons WD 2-10-0 and i do have the castings but always worried that if they are faulty or i mess up,i can`t replace them.
I think this loco will see me out,that`s if i can lift it!!!! Ex N.London SME,a long time ago.
I've got a copy of the 1977 catalogue, that lists a 5"G Duchess and states that it was designed by H. Clarkson Senior and had four cylinders. It goes on to say, ".......is actually under construction at the present time (mid 1975), 8 drawings are now available and the castings hereunder listed will be available soon."
A full set of castings was £128.42 with an extra £11.10 if you wanted gunmetal cylinders.
I have for some time been putting together a collection of 3 1/2 inch gauge British Pacifics and therefore undertook some research into H. (Harry) Clarkson as the designer of the 3 1/2 inch gauge A3 and A4 in his catalogue. I currently have a working A3 and am putting the finishing touches on an A4 having purchased it as a well advanced chassis, boiler and tender from Station Road Steam some time ago.
This is the extent of my information on Clarkson. If anyone can add to this biography I'd greatly appreciate hearing from them - particularly if they can clarify or add to the details through contact with Clarkson's descendants.
I have also put up some notes on H.P. Jackson under the thread of that name
H. (HARRY) CLARKSON
Harry Clarkson started his professional life as an amateur in 1925, making and entering models in early Model Engineer Exhibitions and contributing to the magazine. He then served and suffered injuries in the Second World War which forced him to give up his work as a Crushing Mill fitter and take up the more sedentary occupation of model engineering when he founded his firm in York in 1945, issuing his first catalogue in 1947. Clarkson quickly became established as a leading builder of model railway locomotives of all gauges. In 1950 Clarkson was joined by his son, Herbert, and the firm became H. Clarkson & Son. In 1951 the business was appointed technical advisor to the Festival of Britain and built nearly all the locomotive models shown at the South Bank exhibition, thereby firmly establishing the reputation of the business. The main expansion post 1951 was in the field of industrial modelling, where the firm had a good reputation and enjoyed considerable commercial success. In the industrial modelling business Clarkson had an addiction to turbines and built many working models for Rolls Royce. Commissions also came from many museums including the NRM in York and Smithsonian in the USA. Clarkson’s was a well-equipped enterprise with its own in-plant foundry (opened in 1962) as well as the usual machine shop and fabrication areas. Such was their reputation that the company was often engaged in difficult, small run engineering work for many larger local firms. Nevertheless both father and son were steam enthusiasts and the range of drawings and castings increased steadily over the years although this work never represented more than about a quarter of the company’s activity.
In early-mid 1966 Clarkson acquired from Bill Jackson, his late father’s (H.P. Jackson’s) drawings and patterns. The Clarkson catalogue of ~1967 (dated by the catalogue referring to the construction of River Mite, see below) included twelve designs in 3½ inch gauge (including 6 of Jackson’s) and two designs in 5 inch and their final? catalogue of 1978/79 included 16 designs in 3½ inch gauge and 11 in 5 inch. Clarkson's had an enviable reputation for high quality, authentically scaled and detailed models in their day, but really only for construction by experienced and skilled model engineers as their drawings tended to be a little vague from the critical measurement point of view. Clarkson’s attitude to model engineers was simply that they should be engineers first and modelers second. Clarkson had the view that a designer should not tell the model engineer exactly what to do rather let him use his skill whereas LBSC told the modeller what to do to produce a running representation rather than a true scale model.
Clarkson’s were the main model engineering contractors to BR and made a number of models for display at mainline stations such as Kings Cross. Also, on the introduction of the diesel locomotives, they produced ¼ scale working Deltic engines for the fitters to train on. In 1966, Clarkson’s built a 15 inch gauge 2-8-2 for the famous Ravenglass & Eskdale Railway in the Lakes District. The name River Mite was revived from an earlier R&ER locomotive. The locomotive was based on the eight-coupled steam driven tender from an earlier locomotive, River Esk, and included a new boiler from the Bedford firm of Gower. River Mite’s journey from York to Ravenglass at the beginning of December 1966 was a spectacular piece of publicity, for she came all the way on a vehicle towed by a steam traction engine.
At their height the firm had some 20 employees, but after Harry retired in 1978 the firm experienced financial difficulties with production ceasing in 1983 and Herbert Clarkson sold the firm in 1984? to a company called Elliott’s Bricks Ltd of Huddersfield. One of Clarkson’s employees, Adam Harris went on to set up Camden Steam Services. Harris kept the relationship with Clarkson’s going by supplying the plans etc for the Jackson and Clarkson designs. The Managing Director of Elliott’s, Mr B. Elliott, was a steam enthusiast and owned a number of 10¼ inch gauge locomotives. He tried running the company as a viable concern but closed the company down fairly soon after its acquisition. Elliott’s Bricks is also no longer trading. Sadly the drawings and patterns for many of the Clarkson engines, whilst possibly still in existence, have not been commercially available for many years, thus Clarkson drawings are rare in their own right these days. Harry Clarkson died on 26th April 1985.

I have been told that Blackgates have acquired the Clarkson drawings and remaining patterns so drawings and castings may be available again soon. I hope so as Clarksons had some nice designs although the drawings are not particularly detailed.
Yes Blackgates have acquired the Clarkson of York designs. They have sent me the list below of the drawings now available. Castings are another matter
