6 bit ring for Leica M Elmarit Summicron 28mm 35mm 50mm 90/2 11604 11879 11809

Description

This listing is for a 6 bit coded flange ring for your Leica M lens
the ring is made of brass, chrome plated
1. Please message me first with the list of M lenses of your interest.
2. I will confirm if I can fulfill your order (some M lens requires a special flange ring I don't have)
3. If your order is confirmed, please go ahead and make the purchase.
4. I will carefully paint the rings, and polish (sand) them when necessary.
5. I will have the rings tested on my Leica M240 before shipment.
Note:
1. Some rings might have a tighter fitting than your original lens. It is OK, you just need to be gentle and slowly mount and dis-mount.
2. Some rings have only 5 screw holes on it. That's because one of the screws is in the position of 6 bit. And it's OK with only 5 screws being used.
