Late reply, just got in. Was baling hay until wheel fell off the baler.

Thanks for the replies all!

E-man,

The rifle is a Canadianicon Mk 1 by BSA. (1896) This new barrel is a commercial BSA, but appears set up for the CLLE, as it does have the hole through the ramp for sight protector.
It also has the taller rear sight cap as in your Comparison photo.
The dovetailed front sight has no numbers stamped on it, but is lower than the one in your photo, more like a L-E No 1 Mk 111 sight.

I am sure you have hit the nail on the head though,..............that this barrel would have had a windage adjustable rear sigh fitted at one time. It came with what appears to be a CLLE rear sight, and I presumed it had worked with that front sight. I can try a few rounds with the 215 gr, to see where they print, but would like to shoot the easier to find 174-180 gr if possible.

Thank you again for all the help.

Bruce Ozman,

Yes, we're closer to 3,00- ft than 2,000, and I know this can add to the equation. :-)

I'll let you know what transpires.....and any suggestions for the nice outside but very pitted and cordite washed old barrel? (It'd been chopped by an inch at some time)

Thanks again to all !
Richard.
