Yea those are Fairbanks, they have gotten harder to find, Fox used them till about 1964, Rupp used them early on, and Bonanza used them as well on the early lighting bolt badged bikes far as the
bike bike makers of that time went. Everyone swapped over to Bendix for some reason even though Fairbanks offered them well into the 1970's and maybe later than that. You can reline them in a pinch, your springs look pretty trashed though, I know another member was on the hunt for the springs when he bought me out of the NOS shoes I had left, I dunno if he ever located a replacement for them or not.
