Yugoslavian deactivated ww2 collection PRICE DROP

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.$4500 shipping on buyer(heavy and long)

M49/57 safety moves, fire selector welded, magazine is removable, cocks and clicks.$1850 shipped

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

I would prefer to sell this collection all together as they are all of the Yugoslavian peoples army and all hold the same crest, however most people only want one so I have priced them each separately. I am asking $7500 for the three together, 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, I am in the market for a fishing boat in the 14 to 16 foot range with 20hp and up outboard engine or along those lines. 
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.
