I assume you're meaning to purchase?No, I don't.All I can suggest is that you check out some of the rare book dealers and ebay from time to time.As the original purchasers are starting to pass away copies are starting to turn up in estate auctions.I've come across two copies, so far, one in each of those locations.
If you're looking for copies to reference, there are 1 copy each at the Washington CO, IN Historical Society in Salem and at the Allen CO Public Library in Ft. Wayne.(I believe Chelsea also provided a copy to the Library of Congress)
FWIW - I've noticed subtle "differences" in Dinn's book.Apparently he included additional material as inserts which may or may not be still there in copies purchased.Substantially the material is the same, but there DO appear to be additional information in some copies that are not present in others.
