Winter Parker Pages
Harry; I included info from a couple of your posts and considered you a contributor. Hick a several other contibutors will also recieve the five complimentary copies.
One figure was compressed to fit into the text and is really a little small. It is attached here at more readable size. Looking at that figure leaves no doubt that Parker's standard twelve ga bore size was .750 - .760 prior to s/n 70000+/-. This makes sense as it is the same as the ID of a paper shell.
We need to do some more measurements to determine if the bore diameter changes co incident with chamber taper.
Dave Suponski has been working with an unfinished barrel, and is looking into Parker's tooling, and changes in tooling.
We also need some bore measurements of Parker competition guns. The two we had available had .740 bores like Super Fox; we need perhaps 10 more guns that have competition charactaristics to see how frequent this is.
Best, Austin
