What was the final year for the round dial, and the final year of the sundstrand drive? Thanks

...now the drive inside from the external appearance is a different matter
I believe that 1940 is the last year that Sundstrand drive machines were built, but there might be one out there with a 1941 build date. Inline exciter motor/generator (MG) machines started showing up in late 1940. The last few round-dial's were built in the beginning of 1945. The latest round-dial that I know of was built in July of 1945. Square-dial production started around the beginning of 1945. I don't know when the first square-dial was built, probably late 1944.What was the final year for the round dial, and the final year of the sundstrand drive? Thanks
...
Speed control / gearbox handles are the giveaway for a Sundstrand VS MG drive.
Modulars have different doors at the front than WiaD or MG.
Visually differentiating WiaD / MG I do not personally have a quick answer for. Someone else can probably point out a simple dead-giveway for that as well.
Mind - I no longer have to care.
I'd Eurotherm-Parker SSD convert all but the Sundstrand, even if the Dee Cee motor was missing. I have spares, y'see...
As to the Sundstrand's space layout, first of all, it does have more than one compartment where an electric motor could be placed. Jackshafts, driveshafts, and countershafts are nowhere near "new" technology.
Likewise, hydraulics, nor continuously-variable drives built on them have not stood still since 1937-38 when the first of those 10EE were still in R&D.
Our highway verges, farms, lawns and construction sites are full of them, mowers to plows, to skid-loaders.
"Something" is out there somewhere living as a hydraulic power unit as could be adapted to improve on the old drive.
And then.... there are 'servo' motors, and their 'by now' very well-known mating power/ control units.
For the most part, they are physically small relative to the old 'large frame' 3 HP unit, though not necessarily on their longest axis.
It would also rank as a first-order heresy to perch a final-drive motor ABOVE the 10EE as if it were an 1870's lineshaft cone-head conversion, then store canned cat food in the former 'tank' to keep it from toppling over in a nearby domestic argument.
But d'yknow what?
The spindle doesn't actually give a shit what particular tribe of third-party heathens is motating it, so long as they have big enough balls, can run at a wide range of RPM, and don't kick up a vibratory fuss doing their job.
10EE would still make same chips just as accurately as the rest of the machine could deliver.
