I have been gone for a few days and you all have ran with this. I am beyond impressed with the knowledge. I stumbled on this site while researching my gun and found a previous post about the AB marking. I had to join. I am in IT and love soaking up knowledge. Anything else you find please post. I have learned a ton from this site. Thank you all for your posts. It helps me kinda bond with my Grandfather more as he has been gone for 25 years and learn a little about he had. He had a stroke in 77 and couldn't speak. So asking him questions about his various fire arms was hard. This discussion means a lot to me.
