Guys
I will see what I have on these various artillery trailers, but it may take me a while to get organised!
Never say never! In the course of looking up some pics of the No 24 trailer, I came across a pic of (according to the caption) Canadian gunners training on the Martin Parry conversion of the pole trail 18 pounder - and the limbers are clearly the No 27. Mix and match was obviously the order of the day!
