[R-1051] Frequency Standard Modules

[Geoff Fors]

Just curious if anyone can comment on the differences and interchangeability
of the frequency standard modules in the R-1051 B through H-suffix models.

I have modules which I think are from G or H models, because they have a
window on
top marked "index"  as well as the 3 position switch and the coarse-fine
holes, and carry FSN's of :

6625-01-055-5294 and
6625-01-168-9757

I haven't had a chance to pull the standard module out of my "B" model to
check the differences and was wondering whether anyone has used these style
modules in a B model.
