I have found the following websites useful/interesting and recommend them to you with the caveat that I have no connection with them (unless stated) other than being a satisfied customer. They are not all connected with violins! I take no responsibility for the content of these websites.
I have known Catherine for many years and admire her dedication to the cello, and in particular her desire to make cello playing better for others! It mirrors my resolve to teach bow making. Her website will show you all about her courses.
This is where I used to run my bow courses, before a change of curator forced me elsewhere. It still has a fantastic collection of instruments, mostly woodwind but importantly also the bow and tool collection of William Retford, my grand-teacher. Administered by Oxford University it is open to the public, but beware the opening hours/days may change according to term times.
V-CC – is the Veteran Cycle Club, if you happen to like restoring and riding cycles. Don’t let the ‘Veteran’ put you off – they do ‘Mountain Bikes’ too.
The Cello Museum: https://www.cellomuseum.org
Brenda Neece set this up and I contribute the occasional bow article, but it's far more interesting than that! A superb idea because there you can look at cellos all over the world, then if you decide to visit them 'for real' the incentive is there.
