[time-nuts] Re: Help ID'ing Frequency Standard

[Jeremy Nichols]

None of my older HP counters, standards, etc., have 5110 part numbers. A 1
MHz standard would date from the early 60s—the 5245L counter was introduced
in ‘63, I believe, with a 1 MHz standard. HP shifted to 5 MHz standards
later in the 1960s. A 5110 number definitely puts it in the Frequency and
Time (02) division, probably before the division moved to Santa Clara from
Palo Alto.
