A friend is a model railroader, whos interested in depicting rolling stock from the early 1900s-to-WW-I era. Hed like to do some HO-scale flatcar loads of US artillery pieces, like the M1897 or M1892-A2 75 mm cannon. Are any such pieces or similar WW-I era guns available in 1:87, 1:76, or 1:72 scales? I cant find any listings for appropriate ROCO models. Are any such small-scale artillery models available as plastic or resin models?
And yes, Google is my friend - just not as helpful a friend as I had hoped for this esoteric topic. And I'm posting this inquiry to other sites - no need for multiple replies if you see this again elsewhere.
