Gentlemen, I thank you one and all for the responces as well as the generous offers to put a spare mic in the mail and send it all the way to the Canadian Arctic to a person you have never had the chance to actually meet.

Had a few pints and went over plans with my friend last night. He is going to replicate the Haven 72 for me. We are going to purchase the lumber tomorrow and I'll have to do some searchingly for nice hardware - hinges and handles.He assures me it will be ready in time for our move into the new condo the end of August.
