Hope that I can find out some information about this critter. I have been told that Lyman made a roll crimp device that would roll crimp paper hulls. It was about three inches long and when the handle was pressed down the stem part would twist back up through the mounting nut and when the handle was press back up the stem would twist back and complete the roll crimp.
I am looking for one in 12Ga and 10Ga, if this critter is real.
If you can help with any information please e-mail me at:

Thanks for your time,
