I picked up this $5 Gents Saw, and boy was it rusty and pretty dull.
Took it apart, gave it a soak in vinegar, and did a lot of scrubbing with the wire brush, before wax pasting the blade, then cleaning up the handle and also giving it some wax paste love.
It definitely needs a sharpen, but with that hard work, its looking great and will be a lovely little saw to help me along in doing joinery!
