Have looked at the OWWM page
My cat.# is 28-290 and the serial # is DG-9965 Called Delta, they are sending a manual for that model # but she said the serial # meant 1999,6th. month,5th. day. This saw, to me at least, looks like it has to be older than 1999. It looks a lot like this one, and the stand as well,at the OWWM site, And has that style belt guard. Also the same old fashion looking knobs, like old sink faucet knobs. Says this one is from 1967
