Re: Mallory Vibrator for the Wireless Set No. 52

i have just discovered two different references in the 52-Set Manuals for the vibrator used in the Main Supply Unit and the ZE-12 Remote Receiver Supply.

These two references are the following Mallory Stock Numbers:


I am thinking one of them must be a typo, but do not know which one. Compounding the problem is both of my working vibrators only sport a Canadian Marconi Company Part Number stamped on the top of the can. And just to rub a little salt in, I no longer have an old Mallory Catalog to look the numbers up in.

Anyone know what the correct Mallory number for this particular vibrator should be?
My guess would be G640C for correct vibrator. I can't imagine Mallory getting into the 6000 range!

(Especially since the WS52 and WS19 Mk3 were designed and in production within a year or two of each other.)
