Dear Stuart,
at least the 13-pole male and female units are still well known all over the continental scene, because of their affiliation to Ullrich Tuchel's famous(!) connector product line.
Tuchel belongs to the descendants of the Reichsrundfunkgesellschaft, where he was one of the leading engineer-personalities in the construction department, learning a lot regarding the practical problems within the fields of all connector types. With these experiences he founded his own business, creating the famous 'Tuchel'-audio-connectors, crossbar-(patchfield-)connectors and the standard connectors for that 'miniature' mixing-desk-norm-cassette system, designed by the Zentraltechnik des NWDR (predecessor of the IRT) and used by the German Öffentlich-rechtlichen Rundfunkanstalten since the mid-1950s. The cassettes were made by Konstantin Danner in Berlin, the electronics came from different vendors. Ullrich Tuchel provided them with connectors. These connectors were delivered in different sizes; the regular cassette-connector had 23 poles; your Philips-machine uses a smaller one with 13 poles.
Tuchel sold his company in the late 60s to Amphenol; they went on to manufacture his connector-program as long as the German Radios needed these connector-types. When the German Radio left the "Braunbuch"-traditions behind, Amphenol gave up the production of Tuchel's connectors step by step.
Even though the bigger 23-pole-connectors were made probably in Myriads, they are quite rare today, appear for remarkable prices in the 'Epay'-collection. 13-pole connectors are even rarer. I have two original, new (=unused), but caseless units, which will complement your connectors...
The Tuchel-logo, by the way, must be stamped into the broadside of the connectors. It symbolizes his fundamental idea of the 'self-cleaning contact-system'.
