There may be more than that! I have a hazy memory of multiple manufacturers, each with their own variation of markings, but I can't remember which ones I have in the collection. There was certainly Jelco, but also ZL&T (Zephyr Loom & Tool) and MSU (Montreal Suspender & Umbrella), plus various manufacturers in the USA (for Lend-Lease, probably all for WS19 & WS48 issue).
The actual "Satchel, Signals" was a range of at_least_ 12 distinct types for different purposes (I don't have all of them, and one is a mystery at present).

The original "Satchel, Signals" replaced the leather "Bags, Telephone Receiver" and "Cases, Message Book, Mk.IV" sometime prior to 1940. It soldiered on (Sorry!) until the 1970s, I think, going from khaki to "44 pattern light green", to "58 pattern dark green" and being renamed "Haversacks No.1", and there may have been a nylon/polyester version later on.
The US and Canadian versions were a much thinner/lighter material, rather then the British '37 pattern cotton canvas used for web equipment.
Best regards,
Chris. (Still wondering what No.8 was intended for, it's small, zippered, and has a DMC/VAOS section of Z5 which is "Bomb and Mine Disposal Equipment" AFAIK.) I'm still looking for info/examples of Nos. 4 (mine detector backpack with a large cable entry hole on the bottom), 9 & 11.
