Help identify this track stop please

[WhatThe]

Hi, I'm new here, and to sailing, and I have just acquired a 1975 Jim Young Mandrake 33, a New Zealand design. It has these track stops on the main-sheet track. I can't find them anywhere, even searching through manufacturers, and I tried a Google Lens search of the picture and nothing... I bet someone here would know by sight what it is or the manufacturer. Where do I get this thing? The track is 36mm wide at the top. I need a new one because the plunger pin is bent in this one and its jammed in the hole.

Thanks

Are you able to get it off?

I don't recognize the manufacturer but being from a 1975 boat I would not be surprised if it is no longer available.

If you want to keep it along with that system, is look at having one made for the boat. I'd look at how possible it is to save as many parts of the original as possible and make the parts that need replacing.

Good luck
