Thanks kuduae, I've taken the gun apart and all action #'s match, the DSTs are integral to the bottom metal and not a separate unit, there is an eagle with up raised wings on the barrel. I thought at first the full rib was an add on but it's an integral part of the barrel front ramp and all. The bore is near perfect - sharp and bright. Anybody have any idea about the Ideal Gun stamp. The only thing I found is some reference to Marlin but I fail to see the connection unless of course the gun was made for / sold through Ideal Gun? --- John303.
