Ah, but which one?
I found this
list Tom Albrect put together
Maybe a Sheffield or Canterbury ?
RA-103 Chatham - trapezoidal table model "doghouse," picture in Rider vol. 1
RA-103 Savoy - presumed same cabinet as RA-103C Savoy; Rider vol. 1 mentions AM tuner and phonograph in this model
RA-103 Meadowbrook - console, mahogany, no doors, screen on left, speaker center bottom
RA-103 Sutton - ? (Is this a typo in the Rider index?)
RA-103 Stratford - ? (Rider vol. 1 says this is a table model, and all parts except the wooden cabinet itself are common with the Chatham; Rider also says "The Stratford is easily recongizable by the doors which cover its front panel.")
RA-103C Savoy - console, mahogany, with doors, screen in center, AM tuner on left, FM tuner on right, phonograph lower right, speaker lower left
RA-103C Winthrop - same as Savoy, but in knotty pine
RA-103D Rumson - rectangular table model, with square tuner window; picture in SAMS set 93, folder 4
RA-103D Sheffield - ? (Rider vol. 3 mentions a 10 inch speaker for this, so it should be some kind of console)
RA-103D Canterbury - ? (Rider vol. 4 says it has the same speaker as the Sheffield, so it must be some kind of console)
