The Old Town canoe with serial number 18030 is 16 feet long with short decks and shipped in 1911 which is a bit early for diamond head bolts. The only 17 foot long canoe in the 18030x series with long decks is a Molitor with number 180300 but you probably wouldn't confuse this with an Otca. My guess is that you have the one with serial number 118030 which is a 17 foot long, CS (common sense or middle) grade, Otca model with red western cedar planking, open spruce gunwales, twenty inch decks, and a keel. It was built between June and August, 1936. The original exterior paint color was dark green. It shipped on September 10th, 1936 to Sunapee, New Hampshire.
A scan showing this build record can be found by following the link at the thumbnail image attached below. This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. A description of the project to preserve these records is available at http://www.wcha.org/ot_records/ if you want more details. I hope that you will join or renew your membership to the WCHA so that services like this can continue.

118030 must be it. The first 1 is almost completly invisible on both ends but all the info on the build card matches up perfectly. So 1936 Otca it is. It will a challange. The good thing is the fiberglass came off in one piece. Thanks for looking it up.
