I picked up this No.1 recently.
I like the idea of a big bore No.1 with a 28in. barrel. A bit heavy, but should be swell for long range fun.
I am not sure who did the work, but they were pretty crafty in using the original sling swivel and barrel band front sight. Just opened them up and rounded the ends. Solder them on and there you go!
Has the usual No.1 issue - safety protrusion is bad on a big rimmed cartridge. Wood is nice though, as many early No.1's have.
