Please help me identify this track stop

[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

I had those on my NZ built Hartley. Take the old one in bits and fix. It is hardly rocket science.

I doubt you will find a new one.

It's the track dimension that are the key to it don't get hung up on the original manufacturer who probably doesn't exist now look for similar tracks.

I have not found any similar 36mm track either lol. I wouldn't mind putting something different on but I can't find anything. I have not even seen any similar track profiles...

Yeah, I just didn't like the fact that the plunger head looks like its punched to squash it over the cap like a mushroom, so it doesn't really disassemble. I could drill it out and get a new pin machined but that's heading toward rocket science. It is probably what'll need to happen though.

Likely custom or discontinued part for 1975 Jim Young Mandrake 33. Check marine salvage yards, vintage boat forums, or contact a New Zealand marine restoration specialist. Provide 36mm width detail.

I think good advice. Thank you.

Update. It's Nicro Fico NF610 1 7/16" (36.5mm) X-Track. The corresponding Adjustable Track Stop NF612 is no longer available. If anyone come across one that could be shipped please let me know.

Get the ftting off the track, file the head off - a lot of fittings were made like this, straighten the pin out so it works, drill and tap the pin, reassemble using a suitable machine screw and repair washer.
Difficult bits are straightening the pin and drilling and tapping. Don't worry if the drilling is slightly off centre !

I do have a mini hobby lathe, which I have little experience on, so this would be a perfect little project. Thanks for all your suggestions and helping me understand how these are made and giving me confidence to start pulling it apart to fix it. There's a gent in California that might be able to send me some that were laying around too, which would be good so that I can slip the old one off and just slip on a new one, then fix the old one without a rush. Thank you.

I tried to give a bit more detail ! Years ago it puzzled me was to how they were put together !

Forgot to mention that there's likely to be a spring in the fitting so take care when removing the cap bit !
