I'm pretty sure they made them up until '71 (at the latest); I think there are some threads about the history of the models that you can search for, and also possibly some brochure pictures from way back when. I noticed your boat still had the badges on it- check and see if they match the ones in the thread I posted (I found it interesting that they referenced the original boat company (Coburn & Sargent), even after the Aquasport name was being used (and, theoretically, after one had bought out the other). Your deck hatches and transom definitely confirm that yours is one of the 19-1's, which were the predecessor to the 19-6. I thought my '74 was a piece of history...you got a heck of a vessel there. Good looking boat, and good luck with it.
