Can someone tell me the width & height of the original Old Town 'build sheets'? At least, that's what I call them. I refer to the image you folks provide that shows the canoe's serial #, grade, model, dates for half built, filled, etc. I like to print these out to give folks in case they'd like to frame them. It occurs to me that maybe the sheet size changed over the years. So the canoe I'm interested in now is Old Town 170448, 1960 era.
