Yes, there were 13-gauge shotguns made, but they are quite rare and not commonly found today. The 13-gauge was primarily produced in the late 19th and early 20th centuries, mainly in Europe. Most shotguns are manufactured in more standard gauges like 12, 16, and 20, which has contributed to the 13-gauge's obscurity in modern times.
I can say that Browning started having shotguns made in 16 gauge in the year 1909.Winchester started having the model 12 shotguns made in 16 gauge in the year 1914.so I would surmise that the time frame of 1909-1915 would be the correct time frame for the introduction of the 16 gauge shotguns.
Ithaca made 10 gauge shotguns.
