Well, those AA guns- like the ones that later came from TNW- were built on the kits put together by forum member mondragoon. They use a mix of original and new made parts. I think there were 15-18 components where new ones had to be made. Among those would be the bottom plate, trunnion, possibly the top plate, the belt holding pawl brackets, booster, etc. Of course, both side plates as well. They were nice kits, and I have one I am building right now for a customer.
If I were to assemble an M37 kit now, considering how hard to find most of the parts are, it would not go cheap. I would think you will want to ask in the $4k-$5k range. If anyone wants to try to piecing a kit together these days, you are going to be on a long hunt and paying some money for the more rare parts... if you can find them. I have the makings of another kit, which I will build some day and offer for sale. So that's my input on value.
) and have an idea of what it is worth.
