Though I applaud your search, I fear it is futile. In years past, I remember one of the VFW volunteers telling me that there are believed to be two left in existence, with Clays being the only complete example.
I too enjoyed this game very much and would be all in on trying to re-create this someday when retirement brings more time.
Though it does not look too complex, I constantly underestimate the time involved for projects such as this.
Best wishes in your search,
Rody
