A COACH MAKER’S ROUTER W/ Sound 

Very nice analysis. Nice reference to Salaman. Thanks Chet.

This is an interesting and informative video about the possible use of this anitque tool. Also, thank you for the book suggestions.

And a nice collection of circular planes on your bench…

It's a nice find. Maybe a cheap version of a grooving plane. I think the Stanley Combination planes outdo it. But it'd be interesting to see how much it sold for new against the Stanley of some such equivalent.
