I recently completed a set of detachable Davidson rings and new blocks for a delightful little back action hammer sidelever single by Daniel Fraser. It had been sleeved to .22LR from a rook cartridge.
In spite of the quite curved bore (which was a real trick to set up the 3/4" tube scope I was sent, as it was not image moving), the rifle is a real shooter. Well, it is a Fraser, after all.
A Fraser just does not look like a Fraser without a scope. This one's had been lost somewhere in time.
Needless to say, the rifle's owner is very happy now.
