Thank you for your research. Unfortunately, I had the wrong number. I was sent a picture through text messaging and the reflection messed me up. The correct number is #179041. In the meantime, Lane was going through some old papers from his fathers house and found the original build papers. Our canoe is Design #4, which is exactly what ours looks like. It was half built on Sept. 28, 1967, second varnish on Feb 29, 1968. It was shipped on March 5, 1968 to Fernald's Marine in Newbury, Mass. We are so glad to have this information. Again, my apologies, and thank you for your help.
