Product Description
This is a replacement diopter sdjustment ring for the Bolex H16 Reflex cameras with the 10X viewfinder. This includes the Rex3, Rex4 and early Rex5 cameras. I tested a prototype on my Rex3 and it works properly. It may require light sanding with 200 grit sandpaper in the einterior to provide extra clearance if it fits too tightly. All critical dimensions are accurate to the OEM version. The screw hole is an M3 thread.
