Got in a little more build time on the Spit today after the grandkids left. All the remaining bits were painted and added to the sidewalls. After installing the oxygen bottles on the left side, I took a break and wound up reading an article stating that Spitfire I's only had one O2 bottle and it was half the size of the ones in the kit. The kit part represents the compressed air cylinders for charging the guns on cannon armed airplanes. I didn't feel like cutting them out and hacking them up, and they do look pretty good, so there they will stay.
I experimented with the seatbelts, using masking tape as a medium. I was originally going to go whole hog and do the belts and the restraint cable, but I am really enjoying this build and saw no reason to complicate things. The grommets of the Sutton harness are represented with small dots of brass paint filled in with a dark center. The photos look horrible in retrospect, but from outside the completed cockpit they don't look too bad. If I leave the canopy closed, they'll look even better! I'm going to have to work on that.
Fuselage was then assembled and cockpit dropped in. No fuss at all, unlike the last Spitfire kit I did. I added a photo of that one at the same build stage just for comparison.
