Indestro and Indestro Super Tappet Wrench Obstruction Wrench Ignition Wrench Adjustable Wrench catalog pages from various years:

1935 Indestro catalog pp 8 - obstruction wrench - tappet wrench

1937 Indestro catalog pp 8-9 - open end wrench - obstruction wrench - tappet wrench

1948 Indestro catalog No. 16 pp 44-45 - open end wrench - obstruction wrench - tappet wrench

1950s * Indestro catalog No. 20 pp 26-27 - adjustable wrench - obstruction wrench - tappet wrench
(* I believe the year of this catalog to be 1953 or 1954, based on the patent date for their RHFT ratchet *)

1964 * Indestro catalog No. 22A pp 22-23 - open end wrench - obstruction wrench - ignition wrench - tappet wrench -
(* I do not believe this catalog to have been published in 1964. I believe that Alloy-Artifacts made the same error as the Ebay seller from whom I purchased this copy, which was accompanied by a 1964 price list clearly marked "applies to catalog No. 22A".
(1.) Note that Catalog No. 22A shows the address of Indestro at 2649 N. Kildare Ave, Chicago 39, U.S.A.
The United States Postal Service introduced Zip Codes in 1964.
Compiling a catalog and sending it to a printer is a lengthy and very deliberate process requiring an enormous investment in manpower and money. I very seriously doubt that the executives at Indestro weren't aware that Zip Codes were being introduced that year.
(2) On page 23, note that the shanks on the ignition wrenches are
curved. Now take a look at page 27 of the 1962 Duro-Chrome catalog No. 37M (below), on which you will find ignition wrenches with
straight shanks.
Are we to believe that Duro-Chrome re-tooled and began production of straight shank ignition wrenches, while in some far-off corner
in the same building Indestro was still cranking out curved shank ignition wrenches two years later?
The gap in the logic of that assumption requires a bridge too far.
(3) There are innumerable inexplicable examples of the implausible when one begins the process of picking the gnat **** out of the black pepper.
I will leave it to the reader to draw his own conclusions.
I believe Indestro catalog No. 22A was published in
1959.

1964 * Indestro catalog No. 22MA pp 23 - ignition wrench - obstruction wrench - tappet wrench
(* see notes above regarding Indestro catalog No. 22A. The "MA" was the pocket-sized "mechanics" version.)
