Can anyone identify these ?

Top left looks like Pye 697 to me...

chompy1 · 26th Oct 2014, 8:46 pm

the two on the right look like ITT/KB, but i'm not sure which models, but having said that, the top right hand one looks identical to the original LOPT for my WV-05! Is it for sale by any chance?

Cheers, Paul

Top left- PYE 697, top right KB VC series. Bottom left- Decca as a guess and another guess Rank bottom right.

The bottom left could be an ULTRA. The use of the U25 is a clue but I cannot think of a model. It might be the YE series that covered many models. John.

Top left looks like an AT component (Mullard) and marked 1383 so could well be Pye.
Top right is WV-05 KB I think or similar -label 39/L0/62 and a bit of tape says O/W U/S.
Bottom right again looks KB, label 39/L0/50 could be a VC11 Featherlite or small screen.
Bottom left I don't know. Date stamped 8 Feb 1954

Thanks for the replies everyone.

Hello,

K-B part 39/LO/50 is indeed for the VC11 Featherlight chassis and 39/LO/62 is for the VC51/52 chassis.

Regards,

Top right looks identical to the one in my KB KV024 which has the ITT VC51 chassis. Rest of them I have no idea though!

Thanks again. I think that John has the correct maker, I do not have anything but the red
books for this era,but the LOPT shown in Vol.5 p.574, Ultra VT9-15,VT9-17,is very similar.
