I need some help here, i picked up a used GBB for 50 bucks and i cannot identify it exactly. I know its a Wilson Combat. I know this cause it says it all over the place. It also says "service grade" on it and it is gold. It looks a 45 but i would like to know what model/name it is. If anyone can help that would be great.

Sorry bout the bad pics
