Hi. I bought an old chainsaw the other day, cleaned it up and got it running. It runs well and seems fairly powerful but it is without a chain brake. I don't see any indication there was a brake, but then if it was removed maybe there wouldn't be much sign left? Did they make chainsaws in the 80s without chain brakes? The saw only cost 20 bucks. Was that too much to pay considering no brake? Thanks.
