the reference bag is 10B/2787.
All antenna parts have a reference as 10B/2557, 10B/2556, etc...

Stores reference section 10B is Royal Air Force aerial parts so definitely British.

thanks to you for this first information

So..... are the different lengths for different frequency ranges?
I'm trying to double my radio knowledge.
