[Histonet] AO 820 microtome questions

[Ze Lu]

Dear Histonet Friends,

We just bought a used AO 820 microtome and wondered  if anyone out there has
an "Instruction Manual 820".  If so, would it be possible to email it in pdf file? Also for this microtome, it came with a disposable blade holder. It seemed that the sectioning angle is fixed. Anybody knew how to change the angle?
Thanks!
