There were 3 styles of builder's plates used by the Herreshoff Manufacturing Company. The earliest boats had a rectangular plate of German silver. From 1925 - 1930, a small oval plate was used, and after 1930 a larger oval plate was used. Neither the early or late plates had build dates stamped on them. The middle plate, however, did have dates stamped on them for a period. Somewhere between 1002 and 1070, they stopped stamping the build date. If you have a boat with the small oval builder's plate, can you let us know whether a date is stamped on it or not?
