No supplier has been able to locate this gun. This stapler is used at the factory(DURA) to install convertible tops.The gun shoots a heavy stainless staple.I have removed tops that the installer missed the plastic in the tack bar and the staple actually penetrated the aluminum bar. I use a DUOFAST 1/2 crown gun that is ok but just does not cut it on say a 2005-2014 mustang. The staples just bend over.
