Did a reply to Long Branch serial no. listing and found that my rear sight is not a CDM MKIII. I have a CMk3 on my 56L7473 No4 MK1. Assuming this is not a correct sight for this year (1943) when was this one first used? Any comments?????:dunno:

jerrbear, Most likely it was a Mk.II 'flip' sight.

Long Branch made stamped/fabricated Mk.III sights during WWII. They are just marked "Mk.III". I think the C Mk.3 stamped/fabricated sights were an upgrade that came post WWII and was used on new production 1949-50 rifles.
If it's a 1949 or 50 Long Branch sight it will be stamped with CA as apposed to a C-Broad Arrow mark.
The ones I've observed that are WWII production at Long Branch don't have the " C Broad Arrow" but are marked on the back side at the top with the "B inside an L" manufacturer's mark. They only have a Mk.III on the front top side. The post WWII sights made at Canadian Arsenals are marked C Mk.3 The little catches on these fabricated sights are a weak point. Treat them accordingly. I had a Hell of a time finding complete, original replacements to replace broken ones on shipment I imported back in 2001. I've got a ton of them that need new catches if anyone has a stash. I could fix them all and corner the market!
