A while back, I had most of a Clip Wing Cub given to me. It has wood
wings, (assumed to be Wag-Aero) and what appears to be an early
certified cub fuselage. I can no longer get a bill of sale for the
fuse and wings; how do I get this thing registered as an experimental?
I am an A&P mechanic, so I don't care less about a repairman's
certificate.

Thank you in advance for the advice.
