It's difficult to tell much about the canoe from these photos (I can almost see White's reverse-heart-shaped deck in the left photo), but some of the early Old Town canoes had the same kind of lines, sharp entry and exit that E.M. White (and other makers) used. The I.F. model exhibits these characteristics. So does the early Guide's Special; it had the same dimensions and shape as the 18' and 19' I.F., but was built in a no-frills manner (decks, thwarts, etc. of ash instead of mahogany, maple, etc., and finish was not as nice... utilitarian, as guide canoes were).
There are some unusual features on this canoe for an Old Town, so either this was factory custom, modified after the factory, or mis-identified somewhere between the time the photos were made and Canoeing the Charles: Images and Field Notes From 1902-1912was published in 1996.
My apologies for sounding like I'm lecturing here, but speaking of publishing, it might be wise (and certainly ethical) not to publish other people's work- including photos and captions- to the web. Every time I publish in any book or serious journal, I sign copyright transfer documents stating that the work in question will not be duplicated without permission of the publisher. They're tough on authors; copyright law also protects publishers from the general public.
