I have a chance to buy a cello made by the early English maker, Barak Norman, that is dated 1720. The cello has been "authenticated" by a reputable shop. It is in decent condition, given its age. I have not been able to find much about cellos made by Norman. He is widely accepted as a master English maker of viols and violas da gamba. This cello has the characteristic inlay on the back, similar to his violas da gamba.
What I am trying to find is what is a "reasonable" price for such a cello and any other information that you may have regarding this maker. I know that a lot depends on the condition of the instrument, but a ballpark figure is what I am looking for.
Out of interest, the Dutch cellist Pieter Wispelwey recorded his Bach Suites on a Barak Norman cello, that is set up as a baroque instrument.
Thanks for any help
