I did find that both of these gentlemen show the same address.

Hallo Folks,
Mikes Devour, owner of the silver List, mailbox is full, he hasn't answered 
recent email. Support at Eskimo.com  say that his phone rings but there is a 
generic answering machine message. He lives in south east Michigan according to 
his page https://www.eskimo.com/~mdevour/boatproject.html 
Is there anyone in the area who could try to get something more definite? I 
can't be of much help because I'm round the other side of the world and 9 hours 
earlier than you in USA. 
OK,Tony Moody
