I'm in contact with a seller located around 75 miles East of me, who has a set of old Cyclo brand bottom bracket taps for sale. Before we nail down a price, I'm trying to determine exactly what they are: they are marked RH and LH and both are stamped 36 y 44. He thought they were an Italian thread tap set, but this doesn't jibe with one being LH thread. And neither British, French or Swiss makes sense with the "36" stamp. Nothing rings a bell with either of us regarding the "y 44", unless there's some rare Spanish threading I've yet to hear about...any expert opinions out there?
TIA,
