I'd
love to add the earlier "Bags, Telephone Receiver" and/or "Cases, Message Book, Mark IV" to the collection, but apart from the Royal Signals Museum in Blandford, the only places I've ever seen them are photographs in Australia and New Zealand. (Presumably because they carried on using leather for longer, and may not have taken it abroad in favour of the 1937 pattern canvas webbing, until much later.)
Oh well... I probably wouldn't be allowed to import it into the UK these days (ITAR and Biosecurity regulations) even if I could afford one.
Chris.
