Steve,

I have a Collins with a '51 Contract date.

It looks IDENTICAL to the reference that Craig pointed you to.

The exact Mfr of the unit pictured is NOT "EAC", but is clearly marked 
Teledyne.

Perhaps you could make pics available of yours.  Then the "collective" 
can sort through this and provide input/guidance.
