Dear Benson,
Thanks very much for the information on the 18' Old Town guide canoe.  I'm very confident in the information received is for the canoe I have, as the original owner was my wife's grandfather.   It was from him that we received the canoe.  The one small bit of confusion I have relates to the color.  The build record indicates the color was "G.S. Gray" and in fact the canoe is gray (at least topside, below the waterline is finished bright) but you say the original color is green to which the "G.S" refers.  Can you sort me out on this minor confusion?
Thanks,
Tranoe
