Found this 1972 Boler 13 on Craigslist for $4200. I have no idea as to condition or whether the seller has clear ownership papers. Appears to be a legit listing.
This also on the Northern Mi. Craigslist. About 15 miles from me. We will try for a road trip tomorrow. Since it has a lot of other items in the ad it is confusing. Some one will love it.
