PhysDoc you have found the patent. Thank you. Reading the patent text and viewing the illustration notes the patent is almost exactly like the tool pictured. There is a slight variation on the upper arm of the tool pictured that contains a .742" round end portion. I assume this is an afterthought to the patent illustrated to help insert a wad while loading a shell. I am not quite sure if the tool is meant to crease brass cases or paper cases. I have not tried it on either type. I thank you all . Daryl
Congratulations on what I suspect is a very scarce tool. There seems to be something of a resurgence of interest in paradox and explora guns, so you shouldn't be too far in the dark loading their ammo, do you have a ball and shot gun? I know the solid ammo isn't to be shot through choked guns. I think your tool is probably for paper cases only, I don't see that putting a proper crimp on a brass case, pictures of brass cased ammo I've seen were crimped at the mouth. Good luck
