For starters, does the number 1033 on the left crankcase tell him anything useful?
Bill was kind enough to pass along some information on his purchase:
"This patrol car came from a farm in Western Ohio and had been there for quite some time. At one time (probably many years ago) the father and son decided to try and restore it. They took a bunch of parts off of it and then the father died.
"This should be quite a project. I am going to be struggling to figure out where everything goes and which pieces are missing on mine. At this point I am going to see if I can attempt to collect the missing parts and start on a restoration."
Bill noted that I was incorrect when I guessed (based on pictures) that the Patrol Car has no rear suspension and might not have a differential.
"First, there is a bit of suspension on the back — there are two adjustable shock absorbers. See attached pictures:
"Also, there does appear to be a differential on the rear drive as both wheels can spin independently. This should make cornering much easier :)"
