I am so old school I started in a machine shop on a brand new 11 inch Logan with a cross slide
with a tool post in the front side and another post in the back side. With production work we often timed tools. Timing tools meant facing part with front tool and using the same stop we might put a groove tool in the back to hold length from face of part to the groove location. There were times we would time 2 or 3 tools at a time.

Atlas up through about the 1950's offered a cross slide that came with a 4-way turret tool post at the front and a fixed tool post for one tool at the rear. It had front and rear adjustable stops on the right side. However, it had no compound feed capability so threading with it would have been undesirable.
 
eBay has a Logan double tool post cross slide & 2 tool posts for $150 bucks. It only takes a short time to change cross slides from the standard to the double.
 
I would love one of those to replace my 820's sloped cross-slide. All that great real estate for mounting indicators would be available; now it's useless. Looking forward to seeing your build!

I figure on making an indicator adapter for the front slot. Long t-nut, Noga arm screwed into one end and a thumb screw to lock it on the other end.

A slab of ductile iron the right size is $75 from McMaster-Carr. Anybody have suggestions for other suppliers?
 
One word of caution in the unlikely event that anyone else has a custom back-splash attached to the rear of the drip pan as my Atlas 3996 does. I spent quite a bit of time and not a little money tracking down and buying the Atlas version of the T-slot cross slide only to find that in order to install it, I would have to either remove the back splash, cut an access door in the back splash, or remove the entire cross feed screw assembly (to install from the front) in order to install it.o_O

I wasn’t sure if you were trying to be polite by not saying “I don’t want that”, or if you just happened to miss the suggestion. Lol. They’re both a little shorter than you’d shown, but the cost is comparable to your McMaster quote. I don’t know if having the t slots cast in is really an advantage though. The cutters may last longer without having to get through all the scale. I was quite happy once the scale removing portion was behind me anyways.
 
Thanks. I know about that one, and the price is very reasonable compared to raw material (and McMaster is just about as good as any place I can find).

With my slide all the way out it's exactly 12" to the back side of the carriage. If I go with the full 12" length and the M-DRO to replace my TouchDRO setup, then I can also use the M-DRO embedded magnetic scale kit.

very interesting indeed. Thanks for finding it!
