I'm a pack rat,and whenever I get around to cleaning up a piece of my horde I end up finding something I can't identify,this morning I found a box with a tach cable in it,NOS,the number isDLA400-79-M-DR56. It could be for any number of things,but I think I remember buying one years ago when I started rebuilding my M-2. If a picture would help I can do that. Thanks Bob.
