The family lore is the Mod. 06 passed down to me was originally my Great Uncle's and he was quite a shot with it. Well the SN is 738830 and my Great Uncle Mile's passed away at 17 in July 1931. I have no reason to doubt it was Uncle Mile's rifle, so it had to have been made in 1931 at the latest. I'd love to find our more, but everyone who knew Uncle Mile's is gone now too.
