Both vintage USA and UK Bigsbys came with screws that held the string ball pins in place.

Vintage UK Bigsbys used larger flat head screws (as can seen in the link above).

Vintage USA Bigsbys used smaller allen head screws. Lennon's B5 has the smaller USA allen head screws.

Karl, I'm sure I prefer the roll pins they are using currently, no doubt as a cost-saving measure...but back in the '70s, I had a Gretsch with the old screw setup. Missing two screws and pins. Impossible to find; had to machine stuff up to make it work.
