Hello everyone, any ideas on how to read the identification marks on a 702 yoke? There’s a letter, then a single digit number then a two digit and then another letter. Any help would be appreciated.

The hoop…something like the assembler’s initial, month/yr made and then the inspector’s initial.

Welcome to the forum.

Thanks so much. So B 4 50 J would be April of 1950. Interesting
