Historical sequence - 10E, 10ER, Mark 5 Greenie, Mark 5 Goldie, Mark 5 Goldie with poly-v drive and 1 1/8hp motor, Mark VII, SS INC. Mark 5, Mark V, Mark V 510(2 versions), Mark V 520 with a Mark V 505 in there somewhere and a Mark 2 also(Ignoring the Mark 1).
The Mark 5 was an improvement(?) to the 10ER, the Poly-v and larger moter were also an improvement. The Mark VII was supposed to be another improvement. In many ways it was, but suffered from a couples of design goofs. They all went out of production. Then John Folkerith entered the picture and the rest is 'history'.
Problems were the infamous nylon speed control cam and the nylon gear rack on the way tubes. Add to that the low height in drill press mode(subject to individual opinion). However there many improvements that reappeared with the Mark V 510...
The added vacuum was ineffective(impeller too slow)(but the precursor of the DC 3300).
And then there was the reliability of the power switch.
It has a larger work table(deeper) and can tilt 90 degrees in both directions. The aux table can be inserted into the side of the main table to further increase its width.
The carriage can be 'linked' to the headstock so that can be moved simultaneously. And they can be moved by the crank.
The things to be wary of are the cam, the gear rack, the vac, the power switch.
A Mark 5/V poly-v belt will work, but it is narrower(9 ribs vs 13? ribs). The motor belt is a potential gotcha.
That enough?
Nope! While you're at it, can you explain the distinction between a Mark 5 and a Mark V?
My brain tends to equate the two name variants. But if there is a real difference between the machines (like a Mark VII and a Mark 7), maybe I can keep them straight.
You know, since the Mark 7 sports a DIGITAL variable reluctance motor, Shopsmith could have added even more confusion by calling it a Mark 101 (also pronounced "Mark five") ...

Your words, not mine. Lotsa negative, but more positive.
A Mark 5 is essentially the same as a Mark V 500 function wise.
SS Inc. continued to make Mark 5s until they decided to call it a Mark V. Why/when I do not know, but likely about the same time as the 510 release. Then it became a '500' to distinguish it.
This whole arabic vs roman is confusing and inconsistent. The Mark VII also had a 'Mark 7' label!

If I am remembering right an Edsel had a lot of innovative features on it.

IIRC Edsel's problem was price point.

That sure was beautiful!!!!
Like a Pontiac and Oldsmobile
The Edsel offered several innovative features, among which were its rolling-dome speedometer; warning lights for such conditions as low oil level, parking brake engaged, and engine overheating;[8] and its push-button Teletouch transmission shifting system in the center of the steering wheel (a conventional column-shift automatic was also available at a reduced price). Other Edsel design innovations included ergonomically designed controls for the driver and self-adjusting brakes (which Edsel claimed as a first for the industry, even though Studebaker had pioneered them earlier in the decade). The Edsel also offered such advanced safety features as seat belts (which were available at extra cost as optional equipment on many other makes) and child-proof rear door locks that could only be opened with the key.[9]
