Heliopan Yellow 12 Bay VI Filter for Rollei 6000, SL66 w/ Cool NASA Grip
Here is a nice German yellow filter in a Bay VI mount for the Rollei 6000 and SL66 cameras. This filter is very unique, it has a rubberized grip on the outside of the filter that was added by NASA for easier operation when shooting in harsh conditions.
The filter is in clean condition in the case and works perfectly. The glass is clean and scratch free and the mount is in great shape.
This is a nice one.
