Ditto on the pipe thread repair. Should be four cutters marked 8, 11-1/2, 14, and 18. Check to see if there are any numbers on the cutters. Looks like there is one in the working position and three other packed together in storage.
It's good to know what it is, I have no use for it though. It may go to the classified section now, hope someone can use it.
It will be priced to sell.
Thanks All
