Bore Size
Chuck, Forrest, and all:
My 10 ga measurements are as yours, but are on the edge of resolution on my Stan Baker gauge so I did not use them in the article. After a little my searching through TPS, I conclude that the combination of .810 chamber and .750 bore would accomodate either paper or brass shells, making it possible to distribute and stock Parker guns in American commerce.
Parker order book entries begin with steel type gauge length - ie Dam 12/30. It would be very difficult to miss an 11, if it existed in the serialization data.
Best, Austin
