Have an antique Penn Yan 18' guide canoe with serial number GE-430. All the top trim on this canoe is Mahogany which is not represented by the serial number. The width is definitely 35 1/2 and not 36 and the depth is 12 not 13 1/2 which confirms it to be the guide model produced between 1948 and 1955 but with the Mahogany trim as an extra.. The GES and GEM models produced in earlier years were slightly wider and deeper. A local canoe rebuilder says the lack of star headed bolts used on the thwarts would indicate that it was definitely a post WWII model.... Can anyone tell me more about this canoe? The number 430 would seem to be a low number suggesting it is closer to 1948 than 1955 but that is just a guess... Are order and shipping data available as they are for the Old Towns? The computer link where I found this information is dragonflycanoe.com. Thanks... Harold
