I corrected a text error I made in my table of TBX Navy Type Numbers for TBX-6.

TBX-6   CG -43005-C   [Not CGQ-43005-C]

CG (General Electric) made the TBX-6, not CGQ (Garod).

>I have TBX manuals on TBX, TBX-5 and TBX-8.  The TBX manual was printed by GE on a 1941 Contract with two early 1942 Supplement Contracts.  Ignoring the TBX-8 because it is a different radio, I am trying to pin down the radio's full Navy Type Number for models from TBX through TBX-6.  And to determine what model number(s) the early manual actually covers.  It's title is "Instruction Book GEI 16829 for TBX Series of Portable Radio Equipments.  Which could imply that it was intended to cover more than just the base TBX.  Plus in some places it refers to several of the alternate power supplies (alternate meaning anything but batteries for the receiver and hand crank generator for the transmitter) with a -1 and/or a -2 following the model letters (for example EF-1 and EF-2).

>I would appreciate it if any TBX-(*) owner other than TBX-8 would send me either all of the radio nameplate information including serial number or a photo of the nameplate.  And if you have the time, the same for the nameplates on any accessory/battery boxes and any power sources (hand crank generator, rectifier supply, dynamotor supply, etc.).  According to a note in my database, I once had a radio that originally said TBX-4 and CG-43005-C but the "C" had been marked out and replaced with a "D".

>Also, anyone who has a manual (that didn't come from me) please send the title page info, and how the radio is referred to throughout the manual and on the schematic.  As an example, in one place near the front of the TBX Series manual it refers to the radio as 43005-A.  Elsewhere and on the schematic, it is just 43005.  In the Preliminary TBX-5 manual that I have, in the text and on the original schematic it is just 43005 but on the revised schematic that accompanied a one-page supplement it is 43005-D.
