The wife’s grandfather was a cabinet maker, furniture maker, coffin maker, carpenter, house builder, etc. who cut the timber off his own land, sawed it at his own saw mill and built all the items for his own needs and the “contracted” needs of others. He did not “sign” any of the pieces of furniture that the wife now has …… so I don’t think he “signed” the roll-top desk he made for a customer, …….. the desk the wife tried to buy when she learned of its existence, but the heir of said wouldn’t sell it.
Cheers
