[Histonet] AO parts and Histology equipment manuals

[Djemge <@t> aol.com]

Hi all, this is my first time adding a message. Does anyone know where I can 
find AO microtome and cryostat parts? Also is there a place on-line to obtain 
manuals for some of the AO and other histology equipment? I specifically need 
a copy of a manual for an old AO 855 cryostat. The one I will soon be using 
needs some oiling, greasing, and overall attention.
Thank you for your help, 
Donna
