Hey, if you and the owner and the potential buyer are all happy, isn't that all that matters?
Even if the lady from the Remington Historical Society gave you good information on the SN, that doesn't mean that the receiver and barrel left Ilion, NY, at the same time. Without matching the assembly code on the barrel to the SN on the receiver, you can't come close to confirming the originality of this configuration.
Caveat Emptor!
