Looking at an Oliver 70.  From what I can tell it's a 1940 model.  Engine is stuck with a block repair from freezing, coolant is drained &amp; it still has oil in it.  the exhaust has been covered.  The sheet metal is rusty but pretty straight, left rear rim is rusted out, has fenders with some rust at the bottom with lights.  I can pick it up pretty cheap but it would require more work than I want to put into it to restore it, as I am currently working on several other tractor projects.  What do you think?
