Most have finally been named... the left men's hasn't though I do believe it is an Academy Award I can't prove it quite yet. = )
What are the model letters ladies and gents?
Yeah... I think the case is similar... but I bought it with the box in question and the seller assured me it was sold together back in the day... though obviously I've not seen an ad of it yet... though I personally believe it's probably an AA. I haven't seen an X dial from 1950-51 in any other model.
