Jerry,
Jimmy Clinkscale ran an accordion shop in Melrose, Scotland, for many years, and commissioned his own accordion brand name, which were mainly rebadged Crucianellis. The shop was one of the most revered accordion outlets in Scotland, and was a great loss when it closed down. They relocated to two consecutive premises in nearby Galashiels following the Melrose close down, but eventually ceased trading altogether, probably in the early 2000s. I have no idea whether there was any connection between Crucianelli and Iorio. Accorgans apparently used Elkavox 77 tone generators, whatever that means.
Dont think Id ever heard of an Iorio in Scotland where the OP is based, so he could have trouble sourcing parts for those there. (Nearly said here, but I now live in England).
That Clinksdale came from the factory with the Iorio badge originally, Clinksdale merely changed the grill and rebadged. Its a fairly common practice.
Iorio and Elka shared a similar history, with the Iorio being the root company (the Iorio name was around many decades before Elka existed). Elka later split off, joined SEM for their access to more advanced electronics. The S3 did not use a tone generator, it had everything internalized (I believe it was called the famous L3 board? I will check my original documentation here at home one day) and the footpedal was the AC adapter and volume control unit with a single mono output that normally went to external amplification. The 77 came with the external tone generator, and that continued down to the Elka 83 model (which I also own). I never liked the huge tone generator, as it was a big box to carry around and one was limited to the distance of the cable from tone generator to the accordion... but the sound quality at the time was far superior to the S3 generation of accordions
The tone generator can be seen near the center here with the Ketron X4 just above it:
