Darren, that looks like it might be a Cartezzi type axlebox, as fitted to the Gresley Pacifics, or at least an imitation of one.

Not a Cartazzi because there are no centring wedges, it looks like just a standard radial axle box design to me. The springs are the confusing factor.

I must admit, I thought the design looked like a primitive Pacific-type Cartazzi, but didn't know the design well enough to be sure.
The top of the springs locate into pockets on a stretcher above and I imagine the canted orientation provides control of the lateral travel to keep it centered - when a curve in the track is encountered, the bogie is still free to move laterally and the angled axleboxes introduce a few degrees of pivot.
I'm told the RH&DR locos use a similar design, also that it was used on some Bassett Lowke locos which of course Greenly was involved with, so perhaps it's conceivable some of the more niche castings were shared between his own designs and some BL ones. This loco certainly uses stretchers, bogie and motion bracket castings which must have come from somewhere...

Did you ever manage to soak the old masking tape off the side of the tender, and if so, did it reveal anymore lettering?

I have to admit, I squirrelled the tender away in the workshop and it slipped my mind whilst I have been concentrating on the loco. I'll try and get some time to soak off the old masking tape and take a look. Thanks for the reminder!

In between bouts of activity I found a bit of time to try and soak the old masking tape off the side of the tender. I'm not completely sure it was masking tape - it's certainly very old but appears to have welded itself to the side of the tender with such tenacity that it seems impervious so far to water, ipa and any rubbing or peeling attempts. It's unlike the weedy grip of the masking tape I'm used to! I've yet to try softening it with gentle heat but my suspicion is that the tape and paint are now pretty much one.
However, the tape is fairly translucent and definitely shows LNER and 1127 through it - it's certainly a '11' and not an 'N'
Which makes it incredibly odd - the only LNER 1127 does seem to be an N8!

I know a number of people who have "personalised" their model by numbering it according to the year of completion, the wife's birthday or whatever.
So are we looking for a builder born in November 1927, perhaps...?

Masking tape does weld itself to the surface in time, sometimes in a surprisingly short time. Years ago I was repainting the outside of the wooden sash windows of my house, and applied masking tape to protect the glass. I was going on holiday the next day and didn't have time to remove the masking tape before I went. On my return 2 weeks later, the masking tape was firmly welded to the glass and it was a nightmare job to get it off.
These days I use some stuff called 'HG Sticker Remover' which works wonderfully on those sticky bar code labels. You might give it a try. I don't know what effect it will have on the paint but that probably won't worry you too much will it?

White Spirit is quite good at getting rid of mild adhesives and old masking tape.
It probably won't damage the paint as that should be fully cured by now!!

Thanks for the tips both! I'll try white spirit because I have some to hand and will try HG Sticker Remover if that struggles to do the job. It's reassuring to hear that masking tape has this ability. It's probably an example of what decent quality tape will do - not the cheap stuff I've used in the past. The tender will be getting a repaint so ultimately it doesn't matter. I'd like to take the opportunity to practice a 'what if' situation Darren |

Just to revive darrenes thread , the PLM is now sat in my dining room sans wheels and waiting for the asbestos man to attend yo it given the cylinders where lagged with that lovely heritage insulation what is also interesting is that the driving wheels have been balanced and the weights are cast lead as per prototype. I dont think that this locomotive was built by one person more it appears to of been a comission build by the likes of lowke or jubb

That is some serious engine. That drive to the first axle, is that from the 1:1 example or only part of the model? It looks strange to me for a full size engine (ok, it lowers the reciprocating masses but it increases angularity).
And I love that injector described in the linked SLSLS Newsletter! At last an injector without that ugly (unprototypical?) hump on the top.

The drive to the front axle is taken from the prototype its a novel idea which i dont think was kept for long when the 1:1 was rebuilt.
Its certainly much bigger than i had thought and whilst i am in the doghouse with SWMBO i will have to extend the eorkshop. Interestingly the driving wheels have all been balenced and the weights are cast lead as per the prototype

On the dust jacket of my 1954 copy of Greenlys Model Steam Locos there is a picture of Mr W. P. Stewart of County Durham with a part built PLM 241. If there's anyone from that area on the forum they may be able to track it down, or try the websites of clubs in that area. I think that Mr. Stewart was the builder of the 15" gauge Flying Scotsman that at one time was at Bressingham, regards Ian Having conducted some research it appears that mr stewarts engine is this one. There are a number of tells looking through the greenly books details are shown of component assemblies off the engine which match with what we have. The frames are now stripped down and all the lubrication pipework has been removed and annealed ready for refitment. The cylinders are now clean of heritage lagging materials and the bores have been honed to remove the pitting and buildup of crap that had acumulated over time. The problem i have is the frames are so large they dont fit in the gritblasting cabinet so i am looking for a local firm who can undertake the work sensitively avoiding the hornguides and other bits. Looking forward to getting it back on its wheels though and looking something like. I will post some photos shortly |

Could this thread be moved into the projects board?
Recent work has been focused on the tender which is a steel tank riveted together age hasnt been kind and the bottom baseplate has suffered from rot.
New baseplate cut and there are now 200 2mm holes to drill and i need to source apropriate fasteners to bolt the plate back in place with its rubber gasket.
The crossheads are a conundrum as they are a very poor fit on the piston rods so i am investigating plugging the holes and silversoldering them up before remachininh them to fit properly on new stainless piston rods , the pistons may well be relieved on their ends to give more clearance volume for steam.
