It's a 12" backsaw with a angled back, and split nuts.
I'd like to restore it, but could use some pointers on repairing the cracks int he handle, and cleaning up the rust. I've seen a few people soak in vinegar. I do have some saw files and a Stanley 42X, but so far no saw vise. Any ideas on the odd curve in the spine?
As best as I can tell it's from 1871-1875
