You're right Wojtek - at those prices, they won't sell many, and the kids will starve!
Anyway, I managed to correct the seat without too much trouble, and it now consists of 49 parts! Eight are the kit parts, the rest are the scratch-built harnesses and other fittings. The pics show the seat harness under construction, and the finished seat, with the re-painted parachute harness, and the new harness belts in position.
The cockpit walls have had some framework and wiring added, from plastic strip, sheet, and stretched sprue, and the rear bulkhead has been assembled, with some wiring and 'plumbing' added, again from stretched sprue. Both have been painted or touched-up as required,and a few details picked out and dry-brushed. With this work complete, the cockpit was assembled and cemented into the fuselage halves, which have been joined. Fit overall was very good, and only a very small amount of filler will be needed on one joint, which will probably be varnish and talcum powder. Note that the instrument panel coaming and gyro gunsight have yet to be added; the gunsight will be fitted near the end of construction.
The cannon muzzles have been drilled out, and the nose wheel bay fitted to the lower panel, ready for cementing in place on the lower fuselage; the nose wheel leg has been left off until after the model is painted.
This is it up to Step 8 in the instructions, with another 45 construction steps to go!
I'll post some more pics as I progress with the next stage, which involves the slightly complex air intakes, and the rear fuselage.
Thanks for your interest and kind comments to date.
Terry.
