I have a First Issue DW 445 Super Mag with a 9 1/2" OAL compensated shroud. It also has a low SN and I was wondering if anyone knew about how many left the Norwich facility? I bought it new a few years ago from a friend who never shot it. The local gun shop was asking $50.00 for ammo, a box of 20, so he decided he couldn't aford to feed it. I got lucky and picked it up to go along with my DW 357 SM. Thanks for any info. Stan
