Greetings Steve: I just returned from my Asia cruise and spotted your question. The Gem went through a number of mechanical variations as well as esthetic ones from the caseless version through the last of the keywound Model As. The carriages are not interchangeable and the feedscrews with drive gears are not the same from the first to the last As. The serial number range of the branded case Gem stops just after 36000. So, if the serial is 37000 or later then the banner varnish transfer (decal) label is the correct one and the Gem Special Automatic Speaker was changed to the Model B Reproducer about the same time. (maybe even together at the same time)
There is one seller on eBay who mixes parts and called a later branded case Gem a 'transitional model' which drove me crazy! You cannot have a carriage arm built-in Gem Automatic up in the 36000s when a bayonet in Gem Special Automatic was introduced some 20,000 machines earlier... I hope this helps. Best wishes, Al PS: Above information guaranteed to be 50% correct as I am still jet lagged to the nth degree. -----Original Message----- From: Steven Medved <steve_nor...@msn.com> To: phonolist <phonol...@yahoogroups.com>; phono-l <phono-l@oldcrank.org> Sent: Wed, Dec 5, 2012 10:41 am Subject: [Phono-L] Branded case Gem with Gem speaker If the carriage and the lid is missing how would you tell a branded case Gem from the later Gem with the Model B reproducer? The reproducers are not interchangeable, but is the carriages?
