I have an Alan Stevenson Case for sale - it is the smaller 'curvy' model, in fibreglass. It has a shoulder strap and wheels, so the Cello can be wheeled rather than carried if need be. The case is pretty much like new, I have only used it on a handful of occasions, when I had to travel with my Cello by plane.
It is a really good case - one of the best available, really - and would suit someone who has to travel with their Cello and wants to make sure it is safe. The price is £600, negotiable (it cost around twice as much new). The reason for the hefty discount is that I haven't used the case in more than a year, and it is just taking up space in my (very cramped!) London studio flat. Cash on collection only please.
If you would like pictures of the case, or if you have any further questions, please do not hesitate to get in touch.
