EFCO was created in 1934.
efco makes the cs series saws.before that some made by homelite before that echo etc.efco is a very well made saw.i think the cs46 has removable cylinder not a clamshell design.very well made saws.
Efco makes Efco chainsaws, they are an Italian company. Their chainsaws are excellent pro level saws that compare directly with other top manufacturers. They use to make saws for John Deere until 2007 when JD signed a contract with Stihl. They can found under other names such as Olympic I believe.

John Deere makes there own mowers. That's why they're pretty much the best mowers left that money can buy, every other brand is garbage for the most part. Half the brands you could name off the top of your head are made by MTD these days. Troy-Bilt, Cub Cadet, Bolens, Yard-Man.Jhon deer
