I have inherited this item and don't think I will be able to make good use of it and thought that I'd make a deal with someone on here.
This is a Canadian 1 meter coincidence Rangefinder from Barr & Stroud MK 21 Mod 2. It is in working condition and was serviced in 1993 and I have the documentation on that. It does not have the original box or bag but it does have the original tripod. I will be happy to answer any questions anyone might have.
