Dave, that's a beautiful Bass. When I was researching John Betts concerning a Bass I had here from London, John Furber was listed as one of his makers or 'out workers'. It's still unclear to me if Furber actually worked inside the Betts shop on his own supplying Betts or a combination of both. Later on, Tom Martin tells me my Betts is actually a Dodd. I believe it was T.Martin that ID'd your Bass as well, no? Either way, it held a similar value if not more. I sold it in less than a year to a professional Symphony Bassist. Next to my Gilkes and Storioni, it was one of the best Basses I have played. I am sure your English Bass is right on par with it.
I hope to be able to try your Bass one day. It looks beautiful.. Enjoy it..
