[Boatanchors] Value for Mallory potentiometer sought

[Troglodite at aol.com]

Gentlemen,
 
I have a piece of electronics I am trying to repair for which I have no  
schematic, and no possibility of obtaining one. There is a voltage adjustment  
pot with a switch that is totally fried, and I am trying to determine it's  
ratings. It is marked Mallory P-38320. The switch ratings are marked on the 
 switch, but there is nothing on the pot itself. Does anyone have an old 
Mallory  catalog?
 
Thanks in advance for any assistance.
