That made me lol.
HOWEVER,
Once you turn over the gun, it IS hos here in OH, unless you report it as stolen.
Are you just wanting a paper trail you do not have to follow? This is why I have done the FFL Transfer.
If you don;t care about having someone else follow the trail, just make 2 copies of a paper that has your info, his, and the Gun's Description and S/N, and both sign both. THEN, keep forever I have done this too for friends. SOME, not even that. OH does not require anymore for a private sale that the Buyer being LEGALLY allowed to own the firearm. 21 for a Handgun, no felonies, or restricted by other reason......
How you "transfer" is up to you.

PS - I do not know how much a "friend" can help with this at a FFl. Laws are Laws, and I am SURE the business wouuld not want to enter a "gray" area.
