This is my Gato Class sub from Trumpeter. I added some PE detailing from a set I found online - it was a while ago so I can't remember the source. The barrel of the rear AA gun has been broken in our recent house move so a little repair work is needed once my modelling room is set up.
I have a much larger sub in my stash - a 3-foot model of the SSRN Seaview from Voyage to the Bottom of the Sea. Waiting to get the lighting kit before I start on it.
