Great to see these locomotives coming together, and I am particularly interested in the 2000 gallon tender as I will need to do a couple of these, in 4mm, to run with 3521 class 4-4-0s No. 3529 and 3547 which were seen on the Barnstaple branch in the 1920s.
I have a question relating to the artwork for the 2000 gallon tenders, and that is the width of the water filler 'coffin' at the rear of the tender top. I'm not aware of a GWR drawing which shows this, and earlier kits exhibit differing dimensions.
The Mallard/ Blacksmith kit in 4mm introduced by Fred Blackman in the 1970s, and now available again from Mark Seward has a width which scales at 1'4", which looks too narrow to me, while the Warren Shepherd 7mm kit has a width which scales at 2'3". The Martin Finney designed kit for the 2500 gallon tender has a 'coffin' which scales at 2'6" width.

Ian,
while there are GA drawings in Russell Vol I that show the coffin, none of them have dimensions for the coffin. For the 2000G I have the Swindon GA and Martin's CAD. They all agree on 16mm over the lid, which looks to me like 2'3" over the side plates. The 2500, 3000 and 3500 look like 18mm over the lid which suggest 2'6" over the side plates.
In the absence of an erecting draawing for the coffin, this may be the best we can do.

I've got a Duke and 3 Bulldogs in the stash, yet to be started and when I do get there, I only hope that I can get close to the excellence that you have attained.

Ian,
I’ll have to do a bit of investigating this as my drawing shows circular water filler, your quite correct with the Finney 2500 gal which I have one.

Hi Simon,
Thanks - I guess a key factor may be what period you are modelling.
I see from the pictures of the Duke you posted in 2022 that the locomotive has a round top firebox. I think that the last Duke to have such a boiler (No. 3279 Tor Bay) received a Belpaire boiler in 1917.
According the the drawing of diagram A24/25 2000 gallon tenders in Russell 1 they were originally fitted with a circular (cylindrical) water filler, and coal rails. At some time later the coal rails were filled in with sheeting, and subsequently replaced with more modern fenders and the coffin type water filler.
As ever, it helps if one has a photograph or two of the locomotive one is modelling, at one's chosen period. There seemed to be subtle differences between each locomotive in the Great Western's older locomotive classes.
Good luck!
Ian
