My boat is a 1972 222 flatback and it does not have the window. The window was production on 222s in mid-to-late 70's v-hulls. It may have gone later, but I am not sure. I think it was an option that was targeted at the S. Florida market. I have seen several, and may have seen on on a 19, but the blat was so torn apart, I'm not sure. Remember that a lot of these boats were sold in the NE as well. I found my hull in Massachusets.
