Those two in the first post are TRIMO:
Trimont Mfg. Co. Roxbury, Mass.
Fairly common because they were produced in massive numbers.

"Look like old Stillson or Roxbury wrenches..."
"Stillson" is actually the
type of wrench, not a brand name, per se.
Stillson wrench - U.S. patent #95,744, issued Oct. 12, 1869
Tilson Tool Barn said:
Daniel Stillson worked for the Walworth Company. When he showed the prototype of his wrench to company executives, they challenged him to test the wrench to see whether it or a pipe would break first. The pipe broke, and Walworth put the Stillson wrench into production. Walworth maintained a monopoly of the production of Stillson wrenches until early in the 20th century, even after the Stillson patent had expired. Walworth was unable to establish "Stillson" as a trademark, and starting around 1905 other companies began producing wrenches that they called "Stillson" or "Stillson pattern".
And yes, while Mr. Stillson did "invent" the wrench named for him, the name was never
copyrighted.
The "Stillson" type pipe wrenches were manufactured by Walworth, Moore, Merit, and Oswego, among others.
