The Supreme Model 560 and 560-A Vedolyzers
The Vedolyzer was announced in June 1939 as "Supreme's conception of a new, amazingly fast and complete method of radio service". It was sold separately or in tandem with the model 561 AF RF Combination Signal Generator as a complete dynamic signal analysis system.
In a nutshell, it is the combination of a VTVM, a wavemeter, and a 3" oscillograph, and also functions as a signal tracer and multiple monitoring system. The Vedolyzer was the main instrument of Supreme's new dynamic analysis system called "See The Signal".
This was state-of-the-art for servicing radios in 1939, and with a name like the "Vedolyzer" how much more Buck Rogers can you get.
The first ad I have found for the original 560 is from the June 1939 issue of Service magazine where it is advertised alongside the also new model 561 signal generator.

In the September 1939 edition of Service Magazine, Supreme announced that all three of its new instruments for dynamic analysis, the model 560 Vedolyzer, the model 561 Signal Generator, and the model 562 Audolyzer, were now available for delivery, and that over a hundred orders had already been placed, even before a price was announced. But it doesn't say how many of these were Vedolyzers.

This is an ad for the 560 from a 1940 Sears Amatuer Radio, Test Equipment, and Sound Systems catalog. At one time Sears really did sell just about everything. The image is similar to the other ads, but it gives a full description and is a little easier to read than some of the others.

By October 1940 the 560-A was already being advertised in Radio Retailing magazine, and this January 1941 ad from Radio Service Dealer magazine offers the updated 560-A Vedolyzer in combination with Supreme's updated model 561 AF/RF generator. The 560-A also has a full page devoted to it in Supreme's 1941 catalog.

My 560 is serial number 103 and is the only one I've found in a modern day photograph online, so I'm doubting there are many of the original production still around after 80+ years.
In comparison, my 560-A is serial number 101 and judging from "A" serial numbers and photos found online, at least four or five hundred "A" versions were produced before production ended, which I think was due to the war.

In the May 1941 RSD Supreme advised customers that the 1941 models would also be their 1942 models, so the 560-A was available at least into '42. But switching over to war production may have brought the Vedolyzer to a premature end.
