Gevarm E1 .22 LR Semi-Automatic Take-down Rifle

I inherited this unique and kind of interesting rifle.  It's non-restricted, open bolt, semi-auto, no firing pin or extractor, very reliable, can be converted for standard or high velocity ammo and you can take it down with one screw.  I think it's in fair condition considering the age, the crinkle finish looks like it's flaked off a bit and the magazine has some corrosion. Otherwise it's in good shape. It includes 1 magazine, I believe it holds 8 rounds.

It's a cool rifle but not really one I'm interested in keeping, I figured I'd put it up for sale so someone else can enjoy it. 

Asking $600 but I'm open to reasonable cash offers. I'm not looking for trades.
