Bracket on frame??

[leo verhagen]

Does anybody know what the bracket on the right rear inside of the frame is for? (See red ). Is it original or not? Thanks for your reply.

Leo,

I checked my GPA frame and there is no such bracket. No signs there ever was and no holes to indicate that it could have been added later. I have no what yours could have been used for.

Good luck,

Donovan.
