I don't think that bike is home made, but it has been modified. It isn't ancient, but it has not been well stored. I fear it is beyond redemption. Not sure what the o.p. is after in choosing this frame to be the foundation of their build project but it will need a LOT of hard to find vintage running gear to be road ready. Seriously, cut your losses and invest the energy (and $$) in a production bike from the early 90's onward.
