My wife's family had one similar to that model which they would have purchased in the late '50s or very early '60s. We started dating in '61 and the set had been there for a year or more at that point.

The only difference I can see at a glance is that the set in the auction has rounded corners at the top of the cabinet.

Would the auction unit have a metal cabinet ?

Were rounded corners a common feature of those old Sylvanias ?
