Also if anywuhnyuz have brochures of it with other models and brochures of hose sets and individual attachments for it, please do electronic copies for me. If anyuhyuz have pictures of the MD G23 240 Volt, please post them.

This is so far the only picture I could find of the MD G23 240 Volt Dual Motor Central Vacuum System.

The picture on the MD website at https://builtinvacuum.com/parts/modernday/motors-filters/ is correct and was the latest version of the G23 when it was produced. The nomenclature came about because "G" was the next logical letter in the series and the 23 stood for (2) 3-stage motors. When MD unitized their model numbers, this became the M965h2 which is still available today with (2) Ametek 117123 Motors The 240 volt version has always had these motors thus the original power stats were the same. Yes, It was a beast!!!

That looks like a late 1970s or early 1980s model E...the G23 didn't come about until the mid 1990s when the 116765 and 117123 became available (Grant please correct me if I'm wrong).

G23 will have a wider louvered bottom (though not as wide as on an SV or SVT, which used two 7.2" motors) and a darker blue color.

Here's one I serviced in the north suburbs of Chicago.

Quite a bit less common than the S5 (S900) and the older MD-built triple motor Air-Flo CFM3 units, which this one replaced.

You are correct that the light blue one was a Model E that would have had the 115334 in it. I had to blow the picture up! And the motorshell that flared into the base was from the late 1970 when it was made at Charlie Emdy's garage. Interestingly from the end of 1976 through 1984 I was doing a good portion of the assembly and likely built that unit! I still have the serial number log files with my hand writing if you can find the serial number. That log book went through our fire in 1984 and is still singed around the edges! Yes, the G23 had louvers that were almost even with the exterior of the can and yes, centralvacs 1928, the G23 obtained it's nomenclature in about 1994/1995 after Wayne Emdy passed away. It was mainly created to offer an alternate unit for the dealers who were not able to obtain the S3 Silent Master units that were proprietary.

Do you have a G23 Volt Dual Motor power unit you can do pictures of?

That would be identical to our Model M965. But I believe we only produced it in the darker blue color.
