I had hoped this thread would produce information such as yours, and what others have stated before you. I had done some inspections on the A-250, but wanted to read, and learn opinions from the more informed on the forum. Thanks again.
I noticed today -- after combing through bunches of images this morning and afternoon for any hint to help to solve your mystery -- that the "lip" around the inside top perimeter of your turntable compartment does not occur on all A 250s.
In fact, it seems to have disappeared entirely at some point on the A 250. I did not note any B 250s with this lip.
I've viewed about 3 dozen A 250s from photographs both here and on the web, and I was able to record the occurrence of this feature on 26 of the total sampled.
14 (of those 26) HAVE this "lip" present.
This is how it shakes out for them in my recorded data:
9 out of the 19 Mahogany cabinets I've recorded HAVE the "lip".
5 out of the 14 Oak cabinets I've recorded HAVE the "lip".
The serial numbers of the units I found with this "lip" are all over the place; some earlier, some later.
It makes me wonder whether this "lip" was a feature of the Amberola type cabinets
only, and perhaps the cabinets designed and manufactured specifically for the A 250 dropped this "lip"?
Just a thought, if it turns out that I'm right, this would be a pretty infallible way to determine which type of cabinet an A 250 was housed in, regardless of the Amberola relief cut.
Of course, if I'm wrong...well...back to the old drawing board.
Best,
Fran
