why does it matter if they are original or not? anyway, a 1010A is just a 1010 without
an eyelet forged in. it's had the hanger replaced and brazed in the new position a bit
further back. the seat stays at the top look like a backyard job too, so i am positing
that whoever did this had the most basic frame building skills at best atmo. if you think
that it was the chainstays that were replaced, the dropout is original still, and the lead
area was chopped and channeled to let the wheel drop out more easily. is the rear triangle
on the short side?
