Cheers guys.
Removed kit detail and ejector pin marks, and now cleaning up the cockpit walls. Just keeping the quadrant on the port wall, which (I think) is more or less correct.
The definition of Murphy's Law:
Detail information on the Ki-15 on the net is a potpourri at best, made up mostly of various model photos, a few diagrams, and a couple of photos of the air speed record plane. Very hard to find two sources that agree or show accurately the systems. FINALLY there is a book which sounds like it should answer all the questions! - due for release around October 27, too close to build deadline to be of use to me. Go figure!
Will use the one available 'half-image' from that book however to assist with cockpit layout, combined with afore-mentioned other sources.
Yep, shame I can't see the whole thing though. That book should be a wonderful source of information for future Babs builders, just a shame for me it will be too late for my build.
