[NJARC] Western Electric Capacitor Question

[E. Suhaka]

Thanks, Pete

Now I know what I have.  The flat rectangular shape and lack of standard 
markings made me wonder if WE had them made for some specific 
application of theirs.  They are of standard values but I never saw any 
other caps with this flat and rectangular shape but for these.
