chamber length
 

I recently picked up a 20 gauge trojan with what appears to be 2 7/8 or 3 inch chambers.
It is a mid 1920's gun. Was this chamber length available in trojans around this time period?
To my eye they do not appear to have been lengthened but my eyes have fooled me more than once.

The chamber length of a 20 gauge Trojan in the mid-twenties would have been 2 9/16"

Or 2 3/8".

Parker Bros. "standard" chambering for their 20-gauge guns was 2 3/8 inch intended for the 2 1/2 inch shell. They would on request chamber for the 2 3/4, 2 7/8 or 3-inch shells, but special requests on a gun built for stock like the Trojan would be very unusual. Even though the one ounce progressive burning powder 20-gauge load (Super-X) was introduced in 1922, put up in Western Cartridge Co.'s 2 3/4 inch FIELD shell --

Parker Bros. continued to chamber their 20-gauge guns for the 2 1/2 inch shell into the 1930s.

Thanks Dave,
I know that information on trojan grade guns is minimal at best, but if Parker Bros. were asked to chamber a 20 gauge trojan for 3" shells would there be a chance that it would be lettered?

That is a question for the PGCA historian, Chuck Bishop.
