Here is an eye catching Blue Glass Vacuum Tube for your 1920's battery set!  Not certain of the maker of this tube, but it has a Beautiful Glass Envelope and a good filament!
The tube is "as found" and looks great with its bright blue glass envelope and "Bumble Bee" raised logo on the bottom of the base!  It has an extended, moulded black base and a unique envelope...
It was tested on a Signal Corps I177-B tube tester and indicated 3000 with a minimum of 1500.
I have tried to take good pictures to indicate the physical condition! Ask if you have any questions...
If you collect historical vacuum tubes, this might be for your collection!
Shipping weight will be about 1.5 pounds.
