Christmas 1962-Grandma's set. RCA?

[Dennman6]

Here's a photo from Christmas 1962, showing my grandmother's living room in her 1860 house at 25 Front St. in Norwich, NY. I believe this is a mid/late 1950s RCA Victor, based on the dials on the side of the set & the "pencil box" control door on the front. Can anybody come up with a year and model number? The very real Siamese cat on top of the set is Princess, who died at 14 in 1970.
