Have any of these "odd" barrel length Trojans surfaced?

Oh Lord, I have given you something else to search for. I thought you already had the 30" market cornered for the little 28's :)

Not that I am aware of Dave.

A 30 in. 20 ga has and its owned by one of our own last i knew.

There is no 30-inch 20-gauge Trojan shown in the Trojan Production Statistics table on page 246 of The Parker Story. Does it letter?

I think yes sold in 1917 shipped to ca.

A sincere thank you again to all that have responded. I had no idea that my question would lead to all the intrigue and information that has followed. Obviously, this is the place to be for Parker enthusiasts.
I feel especially blessed to have been gifted this firearm by the previous owner and look forward to putting it back to use and promise to post a pic this fall from UP grouse camp. Gonna be hard to keep my Browning Cynergy cased but this old gun deserves at least one more hunt in honor of all previous owners.

Moi??? You aren't doing so bad yourself buckwheat.:)
