The Jon Hosford gauge is a wonderful tool. However, it needs a stationary rest for the barrel holder. Several internet forum threads have described the use of the Manson gauge while hanging the gauge from a beam or SUV tailgate by a string or rope. That is the way I used mine for a long time. It gives a good reading if you are careful and patient. Jon Hosford's gauge gives better results, but not quickly at a gun show table. Bob could have gotten a rough idea of the walls of the Parker he discusses by measuring the bores and outside diameters of the barrels. Sure, the bores may not be concentric, but the rough measurement would at least weed out an unacceptable gun quickly without the use of a wall thickness gauge. I would like to have a Jon Hosford gauge, if just to give some business to a guy who is extremely innovative, is one of us, and is just a nice guy. Jon shared some secrets with me about the use of my gauges with no expectation of selling me one of his. What could be more friendly than that?

I have one of Jon's gauges and it works great. Easy to use everything fits in the box. the clamp that holds the gauge can fit on any table or you can use the wooden box if needed. You can measure close to the rib rotate the barrels a quater turn measure there rotate again so you measure any part of the barrel that you want. Also you can measure the depth of a pit. Well worth it

Bill I think you are confussing the two gauges. "Jon Hosford's gauge gives better results, but not quickly at a gun show table. " I think you mean the Manson gauge, because with Jon's gauge setup is quick, like I said before, I can clamp it (clamp is in the box) on the table and check both barrels in a few minutes or clamp it to the box that it comes in and use the gauge. I could probably set it up check a couple of barrels and put it back in the box in the time it would take to setup the Manson gauge
