I think you will find it was Richard Allport bought the whole lot. That is what he told me.

Certainly, google brings a connection to Ramco, but it is related to purchases by the late Dave Hicks G8EPR from them.
Even my name appears on the Pye museum (G8EPR) website as donation of various bits of gear!
Dave was a fanatic about Pye Telecom gear! A privilege to have known him personally.
