Hi ALL,
I am now convinced I do in fact have a 1946 CZ45, which means I cannot transfer this "Prohibited" class firearm to a blood family member. It MUST be a Pre-46 manufacture date to allow a family member to get the "12.7" class (inherited Prohib) on their firearms licence (PAL). So, I guess it will go for sale.

Appreciate ALL the great information so freely shared and had a blast searching around with every new tidbit of data! Also learned quite a bit about the CZ line of firearms. Now, to locate the right discussion forum about "deer" class hunting rifles. I am definitely considering a 2.43/6mm calibre bolt rifle to change things up from my Winchester 30-30 Lever Action fixation!!! ("Taken more deer than any other rifle in North America!")
So may see y'all over on a hunting rifle forum soon. Thanks ALL for sharing your knowledge!!! Jim.
