I think you are being very kind. I’m of the opinion that you dont need to be familiar with vintage guns to know what a cracked and broken stock is, let alone a loose action and incorrect chamber size. We’re talking about a dealer here, not some kid that inherited this from a deceased grandparent and has no clue what they just got. They took that gun in from someone and presumably agreed on a value. They couldnt do all that if they didnt know what they were looking at. And I agree that a conversation with the person they bought it from has zero to do with you and your transaction with them. This all just stinks of very poor etiquette
