It may depend on the bolt tool. We have one that appears to be a custom made tool, not a kleindorst. It fits the Hall Dad has as well as the Trophy he has. I believe somewhere he has the original order sheet from the one he has. I know he bought it in an estate, and that gentleman had 4 of the actions. All of them low serial numbers.Al, I will check with Bob.
regarding the trophy vs Hall it sure looks like one but there are differences one being the cocking shroud will not fit into my Hall bolt tool.
