It is a Smith & Wesson Eastfield Model 916 12 gauge. I clean it for a friend of mines. And clean isn't the word!!!! Once I finally put it back together I checked to make sure it pumped I went to the gun range. I loaded 1 low grade shell and when I pulled the trigger it didn't eject it just exploded!! No damage to me physically but my pride has been damaged! LOL Im just trying to see if anyone can point me in the direction on parts, manual???? I can purchase another one for him seeing that it was in my possession (MAYBE). The trigger housing is cracked and I don't think it could be fixed, trying to find major parts or replacements!!!
