  1. What do you want to know?
    I have had several people state that it is an unknown number, another said it was not a valid number even after I posted a photo, another said it could be a number assigned to a large retail distributor, no one seems to have a definitive answer. I have also checked sites about COMPUR shutter serial numbers but none begin with 00. I would like to know the origin and/or the validity of the number.

The '00' may refer to the size of the shutter. I have seen other Compurs with numbers beginning with '00' followed by 5 numbers despite the serial number lists available on the net that say otherwise.

The camera is the second variant BILLY COMPUR 1948 to 1949. I know little about COMPUR shutters, would those production years have had a 00 shutter?

Seems quite plausible, the lens only has to cover 6x9cm.
If you check the size of the lens retaining ring (inside the bellows) you can confim - 00 size have a 25mm diameter ring, with the next standard size (0) up being 32mm.

I think my medium format folders are a mix of 0 & 00 sizes.
