The guy I got it from had picked it up at a yard sale. I didnt know what it was, just that it was mid/late 70's, so I scanned the Museum db year by year till I found a match. What a long strange trip it must of been for it to end up in a small town in mid michigan. Probably snuck over the mississippi in a truck load of Coors beer (if your too young for that reference, see "Smokey & The Bandit").
