These are the BR style as Bob has said, can be a pain to work in miniature.

Thank you Pete and bob. Steam operated it is then. Pictures are a big help to me as I have no idea about them and how they work. My next question is where can I get drawings for them from if any?

Hi Pete.
If the originals were bowden cable operated they were probably ready for replacement when she was first preserved and, as you said, using standard BR parts as replacements, made sense as they were readily available back then.
Bob.

Hi Tom.
Adam doesn't yet have them in his range, but I bought mine about 8/10 years ago, from Hewson Models, now The Steam Workshop. The website is still this: the-hewsons.webs.com/
Bob.
Edit: If you have any difficulty getting them, I have a contact there from when I got details of 1mm slide glass sheets.

I know the 5" ones currently available have a few issues, I have them with the ones currently on the 9f where they don't release to allow water out some else I know has it the other way round. Like Bob says I haven't got them in my range yet but I don't know of anyone off top my head that does them in 7 1/4" but I may be wrong.

Pete which way are you doing it on your a3. And I must say your a3 is looking great Well I'm building her as an A1 '1939' so she will have bowden cable manually operated draincocks..i can't recall when this changed, I've read it somewhere but for the life of me can not remember the date...

I have had a look on some pictures I have when Alan pegler had her and they look like the ones you sent me. Could there be a chance Alan pegler could of put some br draincocks on. As I no he changed the look of her a couple of times???

i think it was later than that, perhaps when Rowland was chief engineer?....I had a quick look at some pictures and I don't think the steam cocks were fitted when she toured Australia but can't be sure without close ups or my magnifying glass which I don't have to hand right now.

Hi Tom.
I have to admit, mine have never been used yet so I can't say how good or bad they are. The loco is still at the chassis stage. I've also got to set up the valves too. I did follow the Hewson instructions for making the valves, and I think they are PTFE valve heads. If they are they may well have to be changed to brass or bronze heads against a PTFE, or silicone O-ring, valve seating, if they stick closed as now made.

I just spent a little time on youtube...watching the loading of 4472 ready for her sea trip to OZ I'm pretty sure that she had manual drain cocks at this time, they are certainly different to those fitted today and I'm sure that I could see the control rod between the two cocks....IIRC you are building her as she was in OZ so unless someone knows better I would be looking at the original setup...do check deeper though just to confirm..
cheers
Pete

I have a picture of 4472 at Carnforth in 1982 and she definitely had bowden cable operated cylinder drains then.

Just spent some time looking just for the fun of it, I believe the steam-operated drains were fitted during the 1995 onwards overhaul. There are pictures of her in 1993 in BR livery at the Dartmouth Steam Railway with the Bowden cable valves

Yes Pete you are correct Roland became Chief Engineer in 1985 just after the loco had been overhauled and remained so until 2004

Hi all. I have seen a boiler on 7 1/4 gauge web site and there is a copper boiler on there for a p2 loco which I am thinking of buying. I phoned the person up yesterday day and he wants 3k for the boiler and casting. I no the builder who built the boiler and no he is a good model engineer. he built is p2 and Made a second boiler to sell. But the boiler is 20plus years old which this is the bit that worries me.
Just in need of advice one this. The things I need to no is would the p2 boiler fit on to my A3 ( not sure if boilers where the same ). OR would you avoid this because of the age of the boiler is self?
All the best Tom
