chokes on a trojan?

[Dean Romig]

It would be extremely unusual that a Trojan would have been made with 30" barrels and those chokes.... but there is probably no way to determine chokes or "pellets" within the 30" test circle on that gun. Measure the length of the chokes and measure the length of the parallel at the muzzle end of the choke. Original Parker Bros. chokes should measure at least 3" long and should have a 1/4" - 3/8" parallel.

A specially ordered Trojan with 30" barrels choked IC/C ?...... I would wager a large pile that it never left Meriden that way.

Either way, that would not be a good gun to use for sporting clays.
