Okay, so I broke down and got a couple of Bliley glass octal 100 Kc
frequency standard crystal, model BG9D.

Now I am looking for data on this part. Google doesn't turn up
anything, other than some nice photos

Anyone have a data sheet on this thing?

It is easy to hook up, but it would be nice to know what drive level
and load it was optimized for.

TIA.

I could only suggest your searching for an old Allied Radio
catalog. I remember seeing Bliley as one of the brands
listed, and there were usually parameters there. You
wouldn't be too wrong with an ARRL Handbook circuit, if
you're going "tube." There's enough "wiggle room" in the
tolerances. Tube-type pre-PLL decade dividers, mixers, and
multipliers weren't even twinkles in the designers' eyes
when those xtals were ground.
