VJ,

N 48587 (1941 ST-M converted) does not have the mini dorsal fin (pic 1109). It is always good to check references. The Paul Matt drawing of NC 14985 (1936) does show it. Wind Canyon Books has the ST-A drawings in 1/24 scale (1/2" = 1") on 2 - 18" x 24" sheets available (rolled in a Tube additional cost). http://www.windcanyonbooks.com/books.php?pid=17&cat=1 They also have all of Paul Matts drawings on 4 CDs ($20/CD) or all 4 CDs on 1 DVD for $50.
