They are made by Efco in Italy ,the former Olympyc, (not misspelled) They are very good saws. They have metal chassis and closed ports. It is rumored they are sold in other parts of the world as other brands, maybe including Pro Mac, which if true, suggest an e-lux connection.
PS: for some reason not understood by me, the 56 runs just about as strong as the 62 and can be had for $50 to $100 less. Now thats comparing a 56, 18" .325 with a 62 3/8, 20". That is about the way you find them set up off the shelf.
I sell them as Efcos.
