You have no idea how many people agued with me on one particular forum, telling me that it was a P17 and not a BSA, when I told them it was a BSA. My father told me it was a BSA, and these gents made me question what my father told me. Should never have doubted my father, he was actually a very intelligent man!
He was the President of the Montreal Skeet Club for a time, he was also a Director of the Atlantic Salmon Association. He was also the best Shotgun wing shot that I have ever seen.
My father also bred and trained English Setters and sold one of his dogs for $28,000.000 USD as a stud dog after it won many big field trials in the USA.
The first time my father took me hunting I was 5 years old, he let me shoot the shotgun and it blew me off my feet lol
