That's a good start, thanks to all!
I assume all mentioned tuners are based on the PCC88-PCF80 valve set.

Interesting to see that Philips/Mullard used a two-step approach for the tuner manufacturing. Apparently the mechanical and electrical assembly was done in a first factory, coded HY, while valve insertion and subsequent tuner alignment were done in the Mitcham factory, coded MK. Does anybody have an idea about which factory this "HY" might be? Alternatively, but less likely, this was also Mitcham, with HY the factory code for unfinished sub-assemblies and MK for complete modules.

Jac, I'll contact you off-line.
