Yours is the gen 3 of this caliber introduced by end of 1922.

Gen 1 appears ca1921, with numbers only. Will have to dig this one out to see if it has the patent stamp on front plate. Can’t recall the patent date, anyway.

Gen 2 appears following 1922 tariff, with added text. “Patent” on back.

Yours is the next make, with updated stamps but still the simple stud carrier.

Gen 4, with the 2 screw stud carrier, followed closely. All before full serial numbers were added!
