Here's a better view of the various Jaeger ring heights. I chose not to dismount the medium-ht rings from the carefully zeroed rifle but the crudely unfinished steel ring in the center is approximately the medium height.

The high rings are intended for the Mannlicher split-bridge rifles & unaltered-bolt rifles while the low rings would appear to have limited utility except with the smaller scopes or the higher-mounted bases.

Michael, have you ever tried to interchange G&H parts with Jaeger? I don't have any G&H mounts at present for comparison but the Jaeger ring mounting appears to be identical in design if not in actual dimensions. Might be worth investigating.
Regards, Joe
