Thanks everyone for all the GREAT info. I greatly appreciate all the knowledge you are sharing. I looked at the Flues on Gunbroker. It is serial #44. Mine is #41. Nice piece! Here are some differences I detected compared to mine. 1. There are no markings on my barrels anywhere. 2. My top rib is solid. 3. Mine has a single selective modeltrigger. Also, there is what looks like a set screw actually inset into the front of the trigger. Is this for adjusting trigger pull? If so, what a great idea. 4. My forend is a one piece job with a pretty good swell to it almost like a beavertail. There is a screw in the front of it like that on a Parker beavertail. 5. The receiver scalloping pattern is different. I'll be posting some additional photos later today. Thanks again for all your comments.
