I've noticed the No. 1 was made in .416 Ruger, Remington, and Rigby. And photos I've seen on gunbroker show some with the Alexander Henry fore-end and some with a different fore-end the name of which I don't know.
My questions. In what sub-models were the .416 No.1 made? And what sub-models had the Alexander Henry and what not?
In particular, was the .416 Remington made without the Alexander Henry fore-end or is that all there is?
