What is that clear dome? On my kit it just sits on top, should there be a hole in the fuselage where it goes?
Joe, it was originally an astrodome (or 'astral' dome) for the navigator to use...since the cockpit didn't have any 'skylight' type canopy windows. Usually seen only on military versions, since civil a/c of the time navigated mostly by visual checkpoints and/or radio beacons.
Even many military a/c had them removed after the war. The '50s-'60s-era RCAF birds of the sort I'm doing still had the 'base' part...covered over...but the domes themselves were removed.
I've seen all three configurations in gunship photos over the years: no dome (or original installation faired flush), just the base remaining, or dome present...you'll have to check photos of the bird you're doing, if available, or just make a 'best guess.'
BTW, here's a nice shot of what they looked like, complete with base mount fairing:
(Props to Massey Air Museum for the photo; more photos of the same on real a/c here:
