Ah yes, I've heard of Hobby Boss. Never built any of their models though.
Let's see...the last submarine models I built were the Red October and the USS Dallas, from the movie. When I was 13. (Longer ago than I care to admit). I can't remember the scale, but I do remember the Red October being a pretty good-sized model. Do you have other sub models around the house that you've built?
