I was recently given a Hotchkiss 25mm carriage that has sitting for a while in a local farmers back pasture. It is missing the barrel, recuperator, breach and breach block and some other little stuff (basically all the important stuff). What is the value of something like this? And, what is the potential to find parts and build this? If I am correct it was a Finnish refurb from what I can tell with a "Korjattu" tag on it stamped 1920/241. Also, what do I need to do to keep me out of trouble since I have NO cannon experience? I am suspecting with the parts I currently have that there is no registration requirement?
So far, I haven't found anything for parts and it is just a yard art piece.
Any guidance, recommendations are welcome.
