If you are truly interested in one of the German beltfeds I would give David Spiwak or MWT a call as their prices are usually market (in my experience), and they have good feelers out there to track one down. Of course MWT has a few of each currently, and they had an MG34 the other day in the 30’s but it was a reweld.
It seems the market for a nonissue, c&r mg34 would be in the 40-50k range today, with rewelds or non c&r guns bringing less.
While we are talking prices, what are mp44’s currently bringing price-wise if the gun is all matching and c&r? Not as up to date on those guns. Thanks
