Now that you have apparently figured out how to post photos, RJ, you should post photos of your Indestro valve lifter and Wakefield fixed socket wrench sets in the Indestro and Wakefield threads. They would be invaluable additions. As I alluded to, they would be the first of their kind posted on GJ.
As for an assessment of the availability of antique tools, in my opinion it shouldn't be an eye of the beholder thing. There are no early Indestro valve spring lifters on AA or here on GJ, and my WorthPoint query reports three sold in the last 5 years. That seems uncommon to me. Maybe you've seen them more often. Just because I happen to have two Vlchek valve lifters (see pic) doesn't make them common. But that's just a matter of opinion, and not worth arguing over.
On preference/usability, you are comparing 1920 lifters to a design no younger than 1938, when Ira Clark patented it (2,119,128).
Everything that followed the first Clark-Feather screw type lifter (CF-12) was either a licensed copy or a variant knock-off.
Snap-on, Herbrand, Lisle, NB, Cornwell, later Indestro, Blackhawk, Wilde, Duro-Chrome, Bonney and Cal-Van ALL got their lifters from Clark-Feather or licensed the design.
Zim, Sunnen, and K-D pursued their own patents in 1943, 1945, and 1950, respectively, with minor variations (e.g., more fingers on the knob, removable lower jack fork, left hand threads) but they followed the basic Clark-Feather design and modified it.
You're right, though, the Sunnen and those later K-D lifters grow on trees.
