Sorry for the delayed response to questions. I am not receiving notices that this thread has been replied to.
The cover is a brown black, or soft black, when compared to something like a cold black of a Canon F-1. The covering is nice and soft feeling and in great shape. My guess is that it has been replaced at some time.
The shutter has given me great results. Firing is distinctly different between 1/20 and 1/8.
I will check back to this thread, but if you want an answer more quickly please PM me. In the meantime, I will try to figure how to receive notices about questions on this thread.
Thanks.
