Here's a photo of my low wall K-Hornet with 3x-9xEFR Leupold mounted on a low rib with medium Kimber rings. The eyepiece end is 1.5" behind the trigger and the position seems perfect for me except it's still too high. It would probably be fine for the average shooter however, since I need much less drop and commonly use trap-dimension stocks on my personal guns and rifles. I intend to change the shape of the rib's nose slightly and to eventually use low rings instead of the mediums on this rifle.
Here's a photo of the three types of Kimber/Warne rings that fit the small dovetail. The plain Kimber type on the left is essentially the same as the later Warne Premier except that the Warne has a recoil lug built integrally into the bottom of its base, to mate into a corresponding deep unsightly groove across the rib's top surface. The center ring is the early Kimber type with the more-delicately-shaped lever; the later Warne Premier levers are much more angular & sharp-edged albeit much more easily adjusted for angle. The knob ring on the right is a later Warne Premier in the rare alloy model; you can see the integral recoil lugs (barely) and also the separate steel claw on the off side, screwed to the alloy ring itself rather than made integrally like the all-steel models. The knob rings and the plain rings remained essentially unchanged in visible shape after the transition from Kimber to Warne, but the lever rings went through several iterations over the years and IMO the later models are less desirable because they feel uncomfortably sharp-edged to me.
These rings were made in low, medium and high heights and I've heard of an extra-high but have never seen one. The high rings will mount a 40mm scope on a long rib with good objective lens clearance. The Warnes were made in 30mm size but I've never seen Kimbers in this size.
As I understand it, the Warne Premiers are copies of the Kimbers which were copies of the earlier Billingsley/Brownells which were copies of the still-earlier and presumably original G&H top mounts. However I've never examined any of the G&H or Billingsley/Brownell rings so can't say for sure. FYI FWIW.
