I made my own once from Copper stripes, because I could not find any. It's not too difficult.
It's a keeper for my bench, not in a hurry but someone should have a dead Fluke 51/52 board with one eventually. Mines in mint condition otherwise just missing a one of the four contacts.
Not sure if you plated/tinned yours but bare copper doesn't sound appealing. If I make one I'll go with nickel plated, though plating it manually is a possibility. Next time I'm scrapping something I'll have to remember to rip off an RF shield or something and cut one to size and test it out as a temporary.
Much prefer the proper part though
