I've got a set of good serviceable MG34 locking cams, discovered these in some random parts boxes I had. I apologize for the quality of the picture, if you need a better look at them let me know I'll have my wife take some pics with her fancy camera
Hows about $45 shipped if in US and we'll talk if you're outside the US?
I can't tell how much ware there is on them. You say they are in good shape I will take them. Send me payment information and I will get you a check or Pay Pal if you prefer.
