[Milsurplus] R-390A and such

[Raymond Cote]

For those of yoou that have aan R-390A with original meters, the 
following site would give you a glimpse as to the half life of the 
material that is on the meter  needles (arm,  hands, call it what you 
want)  I received this address from a friend at the Univ of Hawaii and 
it is interesting to brouse.  I do not know what exactly the needles are 
coated with, but I'm sure I will find out soon as this is read by all.
