I got a motor at Napa that looks identical to the one you get at Chevs of the 40's, exact measurements and all, for under $30.00. Available in 6 or 12 volts.
Richard, try Hammerite Rust Cap Bronze, it's the closest match I've seen. Check out my photobucket pics.
David, I couldn't find screws that looked right, they were too long or the heads were too big, so I chucked them one at a time into my drill and worked each screw head against some 600 grit paper till they looked almost like chrome.
