Thanks for circling around and wrapping up the loose end. I may not like the answer, BUT I do appreciate the effort expended in providing it!

That's too bad. Back in the 60s & 70s when I started tinkering this way, a fellow could go to "Sam's Photofacts" (now https://www.samswebsite.com/ ) and get schematics, specs, et cetera for most anything "electronic." I still have some of the stuff I bought from them, but I haven't found an equivalent for appliances. :-(
Since your curriculum vitae indicates an [aerospace?] engineering background, I am sure you will understand when I say that this is not the only "project" on my [hot] plate (so to speak). Since I do like to eat, the kitchen oven did become the most pressing for a time, but it is by no means a one-and-done situation ;-)
For example, I have a couple of ovens I plan to "sew together" when I get some spare time. (Make them side-by-side units, common heat chamber, common controls, dual elements.)
I do a bit of custom machining from time-to-time, and an old electric range is an excellent way to cure powder coatings; but I need something a bit larger (physically) for some of the stuff on my docket. Being able find element (and control) specs would actually let me "design" the finished oven before I start -- instead of engaging in multiple rounds of "trial and error" (or, as I call it, "burn & learn.") Oh well...

Been there; done that; the element I want to look up always seems to be the one I can't find :-)
One of the local guys said he had a cross-reference; but, he wanted to do the work, not just look up numbers -- or charge on a look-up-by-lookup basis. Unfortunately, having someone else do the work is not something I can afford -- monetarily or otherwise. I am willing to pay to have things looked up for specific repairs; but, for a ground-up design project, that would be cost-prohibitive...

Yup, and as it turns out, the old one was rated at 2585 watts, too ;-)

Actually, it is not.
[The equation I prefer is "(Voltage Squared) / Wattage = Resistance.]
The new element, according to the fellow who "has a cross-reference," is rated 2585 watts at 250 volts. That makes the expected resistance 24.18 ohms. (250*250=62,500 / 2585 = 24.18) That's well within a 10% tolerance.

As it turns out, the new element's terminals are 3/8-inch *shorter* than the old element (I checked before I started modifications ;-) ). They were also 1/4-inch closer together, too. (As mentioned, I took pictures.)

Oh for the days when a fellow could just grab a sheet of asbestos (typically chrysotile) paper and cement it to the part that needed protection. They kind of frown on that, now ;-) These days, exhaust manifold gasket material (available at NAPA) makes an okay substitute.
If you do happen to come up with an "appliance" equivalent for "Sam's" let me know; I'd pay additional for that answer ;-)
Regardless, thanks again for everything.
