Very good price. Let us know how they look. Check where the filament is located within a bulb. Should be high enough to properly light a radio dial. The base isn't brass but shouldn't matter. Notice the site has a lot of information about testing these bulbs vs GE.

Well this is the 2nd time I've ordered a 10 box lot...
The first lot from 2 years ago.. was made by EIKO from Taiwan... and in those the filament is at about the 80% point up in the glass.
The latest shipment is Ablaze Lighting but no indication where it was made... most likely China I guess.
In this lot the filament position is at about the 50-60% height point.
