Welcome to the forum Al,
My unit is post-war, green "Interarmco" box, and I paid about $350 for it. The earlier, Nazi-stamped units command a high price, from what I've seen in passing. One may wind up paying a few hundred more for a matching one from WWII.

I can see why these would have been used as trainers, aside from the economics of the ammo; they usually give lots of practice clearing jams and fiddling with the mag and action! If you found a combo that fits and functions, this is good. I'd have a tougher time selling one that worked.

Instead of removing the original extractor completely, I jacked it out enough to clear the conversion breech block's pathway and held it temporarily with a piece of soft plastic behind it.

I just bit the bullet and negotiated a spare mag for mine, for the convenience of reloading half as often.
