Even if fully operational now, couple weeks' use and it may not be. I'd bargain down from that standpoint. Same would be true even if it was NIB, those materials don't just sit there for 60 years and not deteriorate. Externally though, pristine, couldn't be better. The porcelain tended to hold up but the painted cabinet didn't.
Not sure where 'in the line' grandma's was but it had faucets (no valves though, that was up to user) however the suds saver required you to move the drain hose.
