An internet search yielded the info that 'Ffh.39d' stands for Festungsfernhörer 39 Doppelt as used by the German Kriegsmarine Coastal Artillery. This type of headset plugs into the FF33 field phone and desk phone.

Hanno.

Your item might be all, or part of a small VHF transceiver system developed by Plessey postwar, targeting, I think, training aircraft of the day.

Homemade from pieces of gunsight or periscope?

(I thought it was part of the Telesonic unit to begin with!)

It sure looks it was cobbled together, or at least the visor bit was added.

Case, 4-valve, No.3.

One of those "Multi-Purpose Parts" that was used with different sets:

3 x ARP12, 1 x ATP4 is the WS38 (Mk1 & Mk2) version - it may not have been issued with the fully-sealed Mk.3.

Two cases with ARP12, AR8, ARP37 & ATP4 were issued with the WS46.

(Case, Spare Valve, No.2 (or 2/T) was the WS38AFV spares case and contained a 4-pin 12V vibrator, spare bulb and aerial pigtails.)

Best regards,
Chris.
