Having obtained a Histostat 975C crystat which is in beautiful
condition (never used, we're told), we're looking for a disposable
knife holder to replace the wretched side-clamping knife holder it
came with; I noticed in the list archives that someone recommended
using an AO 820 disposable knife holder.  

Does anyone know of a source for such parts?  Is anyone else
successfully using this cryostat model with some other disposable
knife solution?

Thanks in advance.
