There is only an indication of R.M.S voltage: p-p=2.8.3 R.M.S in the top left corner, but no indication that is is a Simpson meter. Bottom left states 'THE HEATH COMPANY' and bottom right 'BENTON HARBOR MICH.' .

BTW, the schematic shown and the one available here is the UK version, showing a different transformer primary. The US version uses the series-parallel transformer primary.

Thanks for the clarification on both the NEMA5 testing standards as well as the transformer. I imagined that the cable and plug would be tested to well beyond their rated voltage, but interesting to note nevertheless.
Oh, and greetings to you 'across the pond' as well!
