Bruce,
Not quite sure how to know unless it's coded in the hull identification number. Mine lists the place of manufacture on the Coast Guard documentation. Physically, I have noticed that there is a difference on the trim on top of the plywood panel that separates the ice box and the settee and the plywood panel that separates the nav station and the port settee. This trim on some boats has a built in grab handle and on other boats, this trim is simply rounded over at the corners. The profile of the trim also varies from round-ish to more square in profile with eased edges. Could be the difference in model year or place of build. The cabin sole is also different form teak ply to holy/teak sole. The on the coach top, the grab rails range from one piece on older models to two piece grab rail on newer models.
