HW/Weihrauch What Kind of HW Sight is This?

[Bad News Beeman]

Hi all, I recently picked up a set of sights off the Bay that were advertised as HW77. Upon arrival, I do believe the front blade is correct but the rear looks a bit off. Particularly the underside which doesn't look appropriately dovetailed to interface with the recesses on the comp tube. Anyone out there recognize what this rear sight belongs to?

it would appear that it is a Weihrauch rear sight if you compare at Knibbs but the age of the sight could be adding to the confusion.

That is the right rear sight, but it is on the wrong base for a 77.

Anyone think that base is designed to fit on a Weihrauch break barrel breech block?
Maybe a new version that does not require machining of the depression used on the older guns: saves machining costs?

I wouldn't discount anything, but the sight leaf and notch appear to be of the older variety. Came with a few other parts that were of a similar vintage.
