decided to read the rest of your posting
i purchased a 1937 cockshutt 80, which is the oliver 80 in a red coat.
i paid 150.00 cdn for mine,but it needs a complete restoration,incuding tires,block work,head and all the rest that goes with it.
have heard of them going as high as 2800 u.s. in showroom condition.
i guess it just depends on how far you want to go with ti.
