The first thing to get your hands on is the build record-- as a point of historical (and sometimes hysterical) interest. You may already have this, as you know it's a '41. OT 133625 is a 13 1/2 foot lapstrake sailboat, built in October 1941 and shipped that month, on October 27th, 1941, to Fall River, MA. Because it was finished in such rapid order, it appears to me to have been a special order. Maybe the boat was ordered by someone anticipating WWII, who wanted to have a bit o fun before the action began... j/k, but I do find it interesting when a ship-date is so close to an important time in history.
The little sailboat was painted a snappy combination of colors: white, blue and gray on top and red on the bottom... any trace of that? Sounds like a sweet little boat! Have fun bringing her back to life, and post pictures!
