antique radium tipped aircraft toggle switch 11- 22K

Description

You are purchasing
ONE
antique, radium tipped toggle switch used at one time in aircraft.  The switch is a temporary one.... press and hold, when released, goes back to original position.  Tested for continuity and  good.  Might make a good geiger counter test source.  Here are activity measurements:
Each switch produces anywhere from 11-22 Kcpm with probe face centered and 1/4" away from tip
**Measurements taken with Ludlum 12 and 44-9 pancake probe; note that your readings may differ from mine depending on what is used.
You will receive ONE switch with activities anywhere from 11-22 Kcpm measured as described above.
**Important note about shipping: In order to keep surface activities minimal, they had to be specially packaged and cannot be easily combined which is the reason there is a limit of one per buyer.  Thanks for understanding.**
Might make a good cloud chamber source:
