Stanley No 78

A picture of a No. 78, but in better condition than mine.

My father in law gave me a Stanley No 78 to play with. It came from the same heirloom toolbox as the Record No. 5 plane, and is pretty much in the same condition as the No.5 as well. I can feel a little restoration project coming to me!

I wonder whether I can bring this "old rusty" back into a functional rabbet plane.  This made my day, on top of being probably one of the day that I spent the most time working in the shop ever... I've got cuts on my hands to prove it. These cuts are not even caused by my tools, but by the wicked hard edges that Hard Maple can keep on these through mortises cut across 3" of wild grained stock!
