Hi Chris,
What an interesting old saw. I, personally, have never seen anything even close to one like that saw. Glad you posted a picture of it for us. First of all, I wish to welcome you to The Village. There are as many skill levels here as there are people. I want to encourage to to explore around this sight and to participate by reading and posting in the forum. Taht way you will get to know us here and we will have th privilage of getting to know you too. we are a very friendly bunch of people and we live in almost every corner of the planet Earth, If it has any corners. Everyone has ideas of there own, from the best blades to use, the best saw on the market, the best way to attach a pattern to wood and what angle is best for you to mount your saw. Everyone has something to offer others, as I am sure you also have, so jump in and get your feet wet by coming back here often so we all can get to know you better.
Dick
