[Boatanchors] Can you identify this Xtal?

[Philip Atchley]

Hi,
I've been given a 100kc Xtal to use in a crystal calibrator.  It's in a 
very unusual 3 pin "holder". Even though it has three pins and is fairly 
large, I don't think it's in an Xtal oven, two pins appear to be tied 
together.  I've sent an Email to a gentleman with a Bliley website (son 
of one of the founders of Bliley), but haven't heard from him yet.

DATA PLATE INFO:  Bliley Electric Company, Type AR 21W, 100kc, 4749, 
25oC, Made in USA, Erie, PA.

Holder Size: 1 1/2 x 1 1/8 inches by 2 inches tall.
Pins:  3 rather Fat ones in a triangle, like this,
(The 0 represents the pin, I assigned the number)
                                                      01


                                                   20   03
Pins 2 & 3 appear to be tied together had have less than 1 Ohm 
resistance between them.

I presume it's from some military gear as the information stamped on the 
side says 455-1040  Y301.
