I have one of those stored away in the basement, to go along with the stored, vintage gas powered Servel (which needs maintenance & repair). :-(
Hippies ruined the only building suitable for block ice storage, by gutting it to salvage lumber for other projects: it had 18” double wall construction.
As long as Corps of Engineers didn’t interfere, there’s a reservoir close by where ice could “easily” be harvested.
Even as you describe it’s condition, it’s worth GOOD mony. Call an antique dealer to see how much.
