Mike,

They did indeed, and introduced In about 1951 the BSA Hunter, a controlled feed short Mauser type action with integral scope mounts.

Prior to that Parker-Hale built Hornet rifles, some with a flush mounted scope just in front of the action, as well as ParkerRifling other rifles to Hornet using a 1/2” instead of the usual 3/8” O D tube.

The reason I no longer have the 23-D is that I felt I didn’t need 2 Hornets, and kept my Hunter instead. The one I should have hung on to was a cased ParkerRifled Holland and Holland hammerless Rook Rifle.
