I certainly don't have the experience of others here yet, but if what I have learned is correct then the heel pattern and that "M 9" writing inside are dead giveaways that these are NOT CJ, although I cannot remember which makers those things designate. I am sure those with more knowledge than I will chime in shortly.
The "recent images in this thread " is quite interesting. one of my co workers came into my office and was a little shocked. Had to explain that it was just a reamer... you know, used to make holes bigger.
You could always call the manager of Tricker's factory shop (from US: 011-44-1604-630-595). They may have other shell boots in their factory shop. A couple of years ago the manager was David Northfield. He was willing to check the inventory of the factory shop (not all of its items are listed on ebay) and to keep an eye out for what I was looking for.
