The Armaloy Era

Armstrong's earlier alloy tools had been marked as "Chrome-Vanadium", "Alloy Steel", or some equivalent, but in August of 1946 the company began using "Armaloy" as the standard marking for alloy steel tools. ("Armaloy" was registered as a trademark in 1957.)

Since it probably took some time to change over the markings, a beginning year of 1947 is reasonable for "Armaloy" marked tools. Within this era there were relatively few changes in design to allow for estimation of manufacturing dates, but in 1978 the model number system was revamped to use 5-digit numbers. Unless other factors are known, we will use a range of 1947-1978 for Armaloy tools in the older numbering system.

Hopefully further review of the catalogs will help refine the date estimation process.

Tappet Wrenches

For the Armaloy era Armstrong offered tappet wrenches in a 109x series, using the same design with unequal openings and 15 degree offset angles as the older 42x series. By this time the older 40x series wrenches with asymmetric offsets had been discontinued.

Armaloy (Blackhawk-Armstrong) 1090-D 1/2x9/16 Tappet Wrench

Some earlier examples of Armaloy tappet wrenches can be seen in tools marked for the Blackhawk-Armstrong line. These tools all bear the standard Armstrong markings of the time, clearly illustrating that these were really just standard Armstrong production with the Blackhawk name added. Blackhawk Manufacturing was acquired by New Britain Machine in 1955 and the tool production changed after that, providing a 1947-1955 date range for the Armaloy-marked tools.

Box-End Wrenches

Armaloy box wrenches were available in several different configurations, all denoted by industry-standard numbers with a 4-digit prefix to specify the design. Specifically, the 6xxx series denoted short angled wrenches, the 7xxx series denoted long angled wrenches, the 8xxx series denoted long offset wrenches, and the 9xxx series denoted short offset wrenches. An additional 5xxx series was used to indicate extra heavy duty offset box wrenches.

The rough, unplated finish of this wrench suggests that it was probably made during the wartime period, but the "Armaloy" marking would normally indicate a manufacturing date after 1946. To reconcile these observations, this wrench may a very early example of the use of "Armaloy", perhaps an informal marking before the trademark was actually registered.
