Please see all pictures. Boat itself is approx 21 long. If you include entire length of piece it is close to 30 long. It is stickered on bottom. I have translated/researched the label. It does have 1919 on the sticker. I have found a few Ulmer Schachtel wood boats in my research but not this exact one. They just slip in.
