Good start on the old fella Lyle. That is one of their older molds from 63. Yours is a more recent rebox from 2011.The kit before yours was boxed as PT-167. You should be able to build it as that if you wish. one on the items Revell left off the 109 was the 37mm cannon mounted just fore of the pilot house. There are aftermarket 37's made for that kit but I know you were saying you might not build that boat.
I'm going to enjoy watching this come together.
