Thread readers and monitor,
I'm curious about the Merckx Corsa 01 that I purchased decades ago but just rebuilt.

On the BB there is an H to the drive side and to the non-drive side there is F 8556.

The frame was sold to me as a NOS respray in the early 2000s.

Still a Newbie so can't post photos yet...

Any info would be appreciated.

Thank you
