Yugoslavian deactivated ww2 collection

Deactivated collection of Yugoslavian ww2 machine guns. All are old deactivations, barrels welded at chamber, bolt faces cut, welded closed as to not be able to disassemble. 
M37 or ZB30 I have no magazine for it, it’s fire selector/safety is welded, cocks and clicks. Was asking 4500 shipping on buyer(heavy and long), now asking $3800.

M49/57 safety moves, fire selector welded, magazine is removable, cocks and clicks. Was asking 1850, now asking $1650 shipped.                Have a second magazine for separate sale.

SOLD M56 stock folds away, comes with sling, magazine is removable, cocks and clicks.$1550 shipped. SOLD 

All hold the Yugoslavian peoples army and all hold the same crest. It was hard to find a value or recent sale for the m37 so if I am out to lunch on the price and you are a serious buyer I am more than happy to discuss. 
Again for serious buyers I am able to provide more pictures upon request by email or txt. Open to certain trades, partial trades with cash, not necessarily needing to be a firearm, worst I can say is no.
I can be contacted through this site, willing to ship or travel within a reasonable distance if it is for a trade. 
All items are available unless marked sold, first come, first served basis.          
 Thank you for any interest.
