H-4 Bayonet Mounts for tt headshells

[1newbe]

Don't post here much, but lurk quite a bit and get inspired. Been watching some of the tonearm DIYs and wanna start there, don't know if I should post this here or there, so mods if you think its better there please move, don't wanna start a bunch of threads all over the place, my question is this; Has anyone ever found a source for these? Was talking with a buddy about some DIY Headshells and Tonearms but cannot find this part anywhere. Any ideas?

For the life of me, I can't figure out why I can't locate these either. I'm trying to update a AR XA turntable. They made a proprietary type headshell connector, and was keyed on a plastic headshell that always wore out ( well, it has beeen 50 years, nearly...) Anyway, I've been looking for a tonearm tube from a 70's Japanese S arm, and a universal connector to use...and can't seem to find them ( been advertising for a broken table on Craigslist for nearly a year.) I missed a Onkyo that my buddy took to the dump by days..( ugh)
Every once and a while i google again, and thought I('d respond.
A small operator could clean up, just with the AR re-builds......
