Need help with a ZB-37 MG

2253 Views 15 Replies 6 Participants Last post by  valley firearms
A friend just bought a post 86 ZB-37 and asked me to look at it before he fires it. What does the selector on the back left hand side do ? I did not have a long time to look at it, but I think the selector goes into to the locking lug. As I think both pieces are missing I will have to look Thursday when I see him . Who ever did the welding on it did a beautiful job on it.
Thank you

I believe that is the ROF selector, fast or slow.
Thank you for the info.

The manufacturer markings should be on the receiver somewhere.
It is on the Receiver just did not have my glasses with me.
Need picture of what the rate selector switch goes into.

I personally liked the slower ROF setting on the '37 - much cooler sound signature.:D
I was wondering if you had a picture of the inside of the back of the receiver with the piece that the selector goes in?
Thank you

Best I can describe it is it slows down or speeds up the ROF by use of an extra spring.
