I put all my Wright ratchets together for a group shot. Don't shoot me, it's a mix of old and new. I'd like to add some older ones but I never see them, love to get my hands on one of the starwheel selector round heads, even a pear head.
Front to rear:
Fairmount B51 (no date code but pre '84, single pawl)
2400 (date code L)
3400 (date code 61, marked pat pend for Tootsie Roll grip patent, original single pawl, rebuilt with twin pawl kit)
3425 (just bought this new yesterday, date code H1G)
3426 (date code 03K)
3428 (date code K, single pawl, looks unused)
4425 (date code 97E)
I have a suspicion the the 2400 and 3428 were either in a kit together, or bought new at or around same time. I got them both looking unused at same estate sale, and have sequential date codes.
