Venner Electronics Modules

[Alexis]

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.

Thanks,

Alexis.
