I don’t know how accurate he is on age but if they’re even just pre mid-80s that should, I hope, yield the right look. I do a lot of vintage/retro recreations and I just *hate* the look of modern PCB stock. Totally ruins it. If these are actual vintage early-70s I’ll be able to make reproductions that visually are difficult to discern from original.
