You might try contacting member dcrane with personal message, you should search his posts, he calls himself a Crane represenative. Hopfully he left some contact information somwhere, I see he has not visited the forum since June 7th. At the top of the page see user control panel, under a tab called Crane Represenative you might find dcrane, Doug Crane I think. This thread would be more appropriate under hand fired, and will probaly get moved.
I see somone posted a manual about third response in this thread Crane 404 help
You might also use search function in hand fired section, searching Crane.
