I still make and sell all of my original riveting jigs. There various post on this site about them. I also make jigs for the 1919 and M2. PM me here or email me at plinker762@aol dot com.
The original trunnion riveter is $145 and the long riveter is $55. These prices include shipping.
The long riveter comes with tooling for 4mm and 4.5mm rivets. It also includes the adapters for the front rivet on the yugo's.
Here is a picture of the trunnion riveter. I can post more photo's if needed.
