That set appears to have hand scribed panel lettering.Most unusual. Was it originally made like that ?
And it's not made by EK Cole either.

I’ve been emailing the seller. He has painted it on himself in an attempted restoration, he should of left it all well alone, shame. Might of been worth a punt in original paint.

What's with this Control Unit A for the 11 set? I've never seen one with this rotary unit. And it's made in the USA!
Or did somebody just mount the transformer in the Control Unit case?

Your second suggestion is correct.

It's a US made dynamotor from a WS19 supply unit fitted in the eviscerated remains of a remote control unit.

Parts only, and only if the dynamotor works.

Here's another ebay item. It says for 18 set or 19 set but it's dated 1940. It's a military ohm meter for testing batteries I think.

Oh good grief. £45, really? You can get them for under £5 at radio rallies, usually.

Instrument, Testing, No.1 is a very basic test meter for line telephony and telegraphy use, back in the 1940s. It coexisted (and eventually replaced) the "Detector Q & I" magnetized needle voltage and current detector used on early telegraphy circuits (that was still being manufactured and issued late in WW2).

Q id Quantity (current, I think) and I is Intensity (Voltage), but I may have them backwards.

Anyway; Instrument, Testing No.1 allows voltage and current measurements on field telephone circuits, on-load testing of 'S' and 'X' cells to determine their usability, and approximate low-ish resistance measurements.

For higher voltages (wireless sets) there was the Voltmeter, Pocket, No.2.

There were a couple of less crude and fairly effective military multimeters, plus commercial equipment for higher echelons, and for accurate resistance measurement there was the trusty Post Office Box and a galvanometer, plus dry cell(s) to suit.

Chris.
p.s. there are a couple of others on eBay for less than a quarter of that price, and it's still too much (really) for what they are. (IMAO, YMMV)
