Brent browsing your site and I came accross some HP part number cross
references on http://www.cs.ubc.ca/~hilpert/e/HP21xx/CTL.html
In an HP "bench briefs" publication dated 3rd and 4th quarters 1990
they listed the hp part number, the makers code and part number

Hi,
I've got here some electronic modules made by Venner Electronics LTD,
Kingston By-Pass, New Malden, Surrey. One is a Transistor Decade Unit
type TS.10/5 and the other just has Type TS 11/HF on it, where 11/HF is
scratched into the metal label.
Opening one reveals a number of Mullard OC44 Ge transistors.
What on earth are they for? I can imagine they're for some sort of
digital machine or even a whole computer, but I can't find any
information about them or the company.
I have a Venner TSA 3336 counter that uses those modules, as well as the
leaflet-style manuals for the various modules.
Pictures and description of the counter and modules are at:
http://www.cs.ubc.ca/~hilpert/e/edte/VennerTSA3336/index.html
The novel thing about the counter is it uses meter-projection displays
(horribly finicky things).
The counter modules are typical 4 flip-flop decade counters, including 4
resistors in a simple D-A arrangement to drive the meter-projection displays.
According to the leaflets the 10/5 is a decade counter good to 30KHz, the 11/HF
is a decade 'selector' (same but has all outputs brought out to a connector),
good to 1MHz.
