45 caliber Thompson purchased in 73 or 76 cant rember. I supplied kit and a gentleman in Vegas did the assembly. A verry clean bore barrel was cold blued still looks good. It probably has only 200 rounds through it .the scope was added about a year or two ago.it is a Malcolm 6 power copy. It shoots great .but it does add to the cost.scope was 500.00 .weight is 10 lbs I would like to get 650.00 you pay shipping.
