Collectors like the petite of old finishes,so in there eye's it would lose value as an antique.Form my point of view I would enjoy a complete over haul to working condition,then use it or let it set in the parlor.If it were rebuilt it would last much longer,maybe another hundred years .All so it does not look in to bad of shape where a guy could put a coat of wax or oil and polish the brass a little,may be replace bellows.
