UPDATE II: This version of the Power-Lock brochure was posted to eWillys in May of 2023.
I hadn’t seen this version of the Cutlas Power-Lock brochure. Given the 1959 date, this is likely one of the earliest Power-Lock brochures. This brochure doesn’t not include a form number.
======================
UPDATE April 16, 2020: The bottom brochure examples show a brochure from 1958, probably Cutlas’ first one. You’ll note that the brochure (and the hub itself) was branded “Power-Lock”. However, the 1960 brochure (shown just below this text) lacks any “Power-Lock”branding. Perhaps someone else knows why, but I can find no reason why. Maybe there was some concern about whether the patent would be awarded? (It wasn’t awarded until 1962).

This Power-Lock was the first hub patented (1958), copyrighted (1958), and sold under the Cutlas brand. As I mention in my Free-Lock article, for reasons unknown, the president of Free-Lock became the president of Cutlas. Even more curious, the last two model of Free-Lock hubs were WL-57 and WL-58.
And, what was the Initial model of the first Cutlas hub you ask? That would be WL-6, shown below (1958 Cutlas Hub Brochure):
