Certainly home made, nice slice of Americana. Without a closer look I'm guessing they were rigged to tip "down". Curious arrangement with two rigs on (what seems to me) one board. Be interesting to know the history behind these relics. Probably won't have much competition if you choose to bid. Wouldn't count on making anything on a flip either. Interesting in a curious way, certainly one(s) of a kind but not likely highly sought after. Unless there's some family member of the maker out there that needs some or all of that legacy.
Thanks for sharing and let us know how the auction turns out!
