The front seat in my circa 1905 Veazie came with no spacers - it was snug against the rails. I'm wondering if this was common for Morris or Veazie. The front seat bolts are shortish and could accommodate space maybe a 1/4" spacer at most. The bolts appear to be original - they are the type that are bent into an L shape and captured in a pocket in the rail and were a little difficult to remove. But I know that someone before me had worked on the canoe at one time - I suppose he might have replaced the bolts and removed the spacers... but why? I should add that the rail caps didn't look like they had been removed.
