This is an original unknown (to me) ignitor for an old hit and miss gas engine. It is in excellent condition with no cracks, breaks, or repairs of any kind that I can see or know of. It mounts with two holes 2.5 inches apart on center. This ignitor may fit several sizes or models of engines. If you know for sure please educate me! The points look to be in good shape. Everything seems to move and function as it should and with just a little work to add some trip parts it should be ready to go to work in an engine. If you’ve been looking for an ignitor like this don’t miss your chance on this one. It will likely be a long time before another one turns up! Let the pictures be your guide. You’ll like it.
