Hi All,  Check the Theatre Organ home page and follow the link that
is part way down the page for a scan of an original Spencer OrgoBlo
owner's manual:  http://www.theatreorgans.com/

Also, check the ATOS Mississippi Chapter knowledge base article for
complete directions on restoring a Century blower, complete with
photographs:  http://atos.stirlingprop.com/kbase/century/index.htm

Don't forget to browse both sites for lots of other good information.
