@ Vancevr:
The numbers on the globe bases I understand to be their individual ANSI codes.
According to https://www.bulbtown.com/default.asp:
1129 = Miniature Bulb Ba15s Base - 6.4 Volt 2.63 Amp 16.832 Watt S8 Single Contact Bayonet (Ba15S) Base, 21 MSCP C-6 Filament Design. 2.0" (50.8mm) Maximum Overall Length, 1.04" (26.5mm) Maximum Outer Diameter. 1.12" (28.50mm) Light Center Length (L.C.L.). 200 Average Rated Hours.
63 = Miniature Bulb Ba15S Base - 7.0 Volt .63 Amp 4.41 Watt G6 Ba15S Base, 1,000 Hour
Note that #63 is a 7v rated globe which I believe was specified thus to deliberately be under-run giving an extended service life for mandatory lighting such as position (aka side & tail) lighting. Nowadays a regular 6v globe would be entirely suitable.
