Wow, that was fast. I appreciate the information. I now have the gun substantially apart. Lots of color in protected areas and the internal parts seem fine so far. The only major problem so far is I have not been able to get the barrels off. I have the thumb lever off and the toggle that runs into the receiver but I can't get the block that slides to the left to release the barrels to move. I soaked the whole thing in penetrating oil over night but it has refused to move so far. Not easy to get to and slow and easy is the way especially since I have never had one apart before so I'm feeling my way. There is slight movement of the barrels and the small block that shows through the bottom of the receiver is also loose so hopefully it shouldn't be long. Got a granddaughter's birthday party today so I'm off. Thanks again for the information. Best Regards, Jack
