I looked it up, Glen Quan died 6/5/2006. No idea if the company still exists.
Look closely at those design patent dates. The BAII was actually filed in 1978 and granted in 1981, so it has expired. The BAIII was filed 6/5/2006 -- one week before Glen Quan died -- but not granted until 2008. It's valid, assuming there are heirs who want to enforce it, but AFAIK no one's marketing a copy of the BAIII anyway.
A patent number doesn't have to be on a product, but it can make it difficult to enforce the patent if you don't.
