Hi

I have a 12 ga Trojan made in 1921.

In the Serialization book pg 46 it says in 1920 the standard 12 ga was 2.5"

I have a research letter but it doesn't reference chamber length.

When did Parker start making 12 ga chambers for 2 3/4" shells?

Specifically, would my Trojan be 2 1/2" or 2 3/4"?

thanks for any info.

Neil
