[vcf-midatlantic] MITS Altair 8800 C&K switches

An odd thing. I was trying to buy some C&K brand "toggle switches" for a
MITS Altair 8800 front panel. I could not find on the Web, a good photo
of it's front-panel PC board "naked" to see the original switches; so I
could buy one of the proper size. Specifically, the length of the "neck"
below the toggle lever.
Does anyone have such a photo, of the unmounted PC board with switches,
or a photo of of the actual real original switch bodies, or a measure of
the physical length of that mounting-shaft? The length does vary.
Just to be clear and exact. I'm talking about the original model of the
MITS Altair 8800. NO 8800a, no 8800b. These switches have a narrow round
"toggle" - not the flat wedge-like toggle on the 8800b and 8800a. And
no, MITS doesn't have a C&K number, and no sketch in their original
manuals (that I could find).
And a Web search for such images is a nightmare. Bunches of faux
Altairs, faux front panels. Some number of original Altairs - with the
front-panel PC board covered of course with the decorative front-panel.
Or poor, low-rez photos from 15 years ago.
I've made a good guess, without disassembling my own 8800. Looks like
11/16 inches from base of threaded shaft to top of same. Looks like a
3/4" net length from the base of the C&K body to the top of the threaded
shaft. These are eyeball measures and are not likely what are in the C&K
1975 data sheets; but these provide clues.
Can anyone measure the damn thing? Or take a clear photo and point me to
it? Looks like I'll haveta take a lot of photos, next time I repair the
