Headford Banjo uke

I am trying to track the maker of Headford instruments. His name is Bob Headford or possibly Whitehead. He seem to have stopped advertising and using Facebook etc in about June last year (2015)
I have some questions about the construction of my instrument, skin tension / repacement, strings etc. (I don't have a problem but would like more information.)
Can anybody help?

I've been looking for any word about him also as I wanted to purchase a uke from him. He looks quite elderly on videos so it could be that he's retired. The worst possibility is that he may be Ill or has passed away, I hope not. It's strange that he seems to have vanished without trace.

They are still coming up on Ebay but only second hand
