The action has been identified ,the guy arguing with the results admits he knows nothing and sharing second hand information it is a wonderful gun built by a great craftsman .i have owned a bunch of rolling blocks I only have one 1902 left it has the rotary ejector my 1897 had the sliding extractor .i have a hiwall that was converted from leaf main spring to coil spring it has the cut in the action for the leaf spring it is not a original coil spring action .i hope you get my point.mark
