Starrett No. 1 Cutters

[KevinGerke]

Hey guys,

I was hoping someone could tell me about what year these Starrett cutters were made?

The patent date is the clue, of course, they were made after the patent was granted. Most patents last 3.5 to 7 years (depends on how much was paid to the Govt) Once the dies were made, they could be used for years, so the end date is anyone's guess. Rough Guess, no more than ten years after the patent date.

At that time US patents ran for 17 years.
