These three Ideal #3 tools illustrate the variation in size that one sees with this model. The tool on the left is in 40-110 Winchester Express; the middle tool is 38-50 Remington, and the right tool is 25-21 Stevens. Note the insert showing that the thickness of the tools also varies with overall size and with the size of the cartridge. The 40-110 Winchester Express tool is seen on the right in the lower panel of the image.
