After inquiring about the 1800 date, the length, and the serial number, I got this response from the seller: "yes we are most likely off on the dates, it was apprasied [sic] by a gentleman from Maine who builds reproductions, it is 18Ft, we can not find a serial number but the canoe was restored abort [sic]15 years ago . . .." He also said he was selling it for his father, who might know more, and offered to give contact information. If someone is actually interested in buying, I would think they would pursue that offer.
Though the listing describes the canoe as a Type 3, the "outside oak stems" that the 1917 catalogue describes as the feature differentiating a Type 3 from a Type 2 are not apparent. Possibly present but covered over in the recanvassing?? Only the Shadow knows!
Jeff, I am attaching a copy of the relevant page from the 1917 catalogue, which describes the types and the usual stem construction at that time. The 1910 catalogue states that all hull woodwork is cedar, and also says that the Type 3 has oak outside stems.
