Found a spare set of early Kimber lever-release rings in the low height and 1" OD. These have the opposed right- and left-hand threads on the levers with no recoil projection on the bottom. See photo, they are the middle style with the lever.

These will fit the early Kimber and Warne Premier dovetail bases and also the Billingsley/Brownell/G&H bases as well as the standard 22RF tipoff 3/8" dovetail.

99-100% original soft blue, excellent in every way, $100 plus $5 shipping.
Regards, Joe
