Thanks Jeff, et al. The Louisville wore MS 21 from sometime mid-1942 until December of 1943 when it received a major overhaul (including totally revamping/repositioning the mainmast). At that time it also got the 32 d6 dazzle scheme. After it's go around with 2 kamikaze hits in the Lingayen gulf, it went back to the US for repairs and eventually set out for Okinawa (April, 1945, when my dad came aboard). At that time it was repainted in the MS 22. BTW, Louisville was hit by yet another kamikaze at Okinawa -- one that nearly took out my dad in his position in Radio II.
I'd dearly love to someday be able to build a 1/350 resin model of the Lady Lou in it's 1945 fit, but I'm not holding my breath!
Thanks again. This forum is great!
