Bruce: Nice to learn the official name of these is Loud Speaker No. 2. On the back of the one I posted, I can see a trace of the original stencil, which seemed to have more information than just the later "LOUDSPEAKER" Stencil. I will have to treat this with some fine sand paper and see what turns up.
Is it possible these loudspeakers evolved through several versions? The set Euan posted seem to have just two terminal posts in the top corners of the front face. My four, and all the others I have ever seen in these parts have four terminal posts as per my original comments. Could these be a later version which provided more application options, or an earlier version for which the lower terminals proved unnecessary? That raises the question these speakers may not, in fact, require all four terminals to be connected in any given installation.
Euan: Thanks for posting your photos. The white outline around the signal button on three of your speakers is something I will have to look more closely for on mine. Yes, mine also lock together in pairs and each came with the 'standard' signals canvas strap that shows up on Fuller Phones, RCU's and the series of field telephones. Those suckers get right heavy fast when paired together don't they!
Hopefully some manuals will turn up dealing with these things one day.
Cheers for now.
