[GreenKeys] Western Union Model 32's

[Larry Tighe]

Howdy Folks,

I have two great Model 32's.  One has the Aux Power Supply number181720 and 
the other does not. The one without has a jumper plug in R2 where the P.S. 
would plug into.  181720 has a sub chassis with a mercury wetted relay 
called "Distributor Wetting".

Question;  Why was this aux power supply added.  Should I add it to the one 
Model 32 without?

Thanks for any cursing, complaining or helpful hints...all attention is 
appreciated.
