Former member here, Brink has a great thread over on WB on restoring saws. He has one on a dovetail saw here somewhere as well - can't provide a link from mobile - sorry.
Here's a link you'll find helpful if the saw plate is too badly pitted: http://www.tgiag.com look around and you can find toothed replacement saw plates as well as handle templates there - even though your handle looks to be in good shape.
