We have an old Townson & Mercer cloud chamber that teacher would like to dust off and use for demo, problem is we no longer have instruction manual, would anybody out there have an instruction manual that they could photocopy and fax to me. Appreciate any offers, Thanks

Different model but it might still be useful.

Thanks Matt, but my old townson & mercer model looks nothing like this new one.

Some have a container on bottom to fill with dry ice others have a spike designed to go into a thermos flask full of dry ice to get bottom cold also there should be a felt ring below top that you use a wash bottle full of Metho/Ethanol to saturate felt ring
