What happened to Bob's Gun Shop?

Anyone have any information on Bob's Gun Shop, Royal Arkansas? I had a confimation of an order for gunaparts from there and they never came. I tried to contact by phone. NO luck.

E Mail contact took months and all I got was a short message that they are no longer in business. I really would like to know if anyone has an idea what happened there. I know Bob was ill. I would like to know if that vast inventory of parts was sold to someone else or if they are somehow available.
Thank you
