"Possibly Val Sneed's, El Rancho Dio, Las Vegas."

I don't think there is anything backing up that thought... though it was suggested (by someone) as Sneed's chips used on games, but still no proof.

It's also been determined that the chips are not VILLA SIERRA - Reno, NV... and that original misinformation was passed on to me -- and passed onward by me...

That listing was dropped.
