Neighbor wishes to sell me the above mentioned trap gun. It has a silver pigeon/dove inlay on top lever and the words Mark II in gold letters on bottom of receiver. Gun is about 100% as owner was a skeet shooter many years ago. Am told it is about a 1972 vintage gun that was built to be competitive with the early BT-99 model. Anybody have any knowledge about the good and bad points of these guns? Are parts still available for them? Thanks again for your input. Bill H.
