Hi Mike. That confirms my suspicion that they were the 6 inch howitzers going by the length of the barrels. Now I'll have to order one of the Resicast 1:35th scale models to go with the new ICM Leyland Retriever kits I now have.
Resicast also do a 60-pdr but it appears to only come with the early WWI type wheels. The photo I have of our 60-pdr's shows they were also fitted with the strengthened wheels.
My thanks, Peter Mossong.
