I have seen a few of these over the years, I don't think any of the ones I seen had a TM. I don't have any history on them. I think I seen one is a reference book, maybe Johnson's, Mine are packed away and hard to get to. The ones I seen had poor quality blades, so never bought one. I always wanted one just because they looked neat.
