Thanks guys as always!
I recently detailed the logic behind the seat to Jon Fellows. I thought some here may be interested...... any comments, suggestions or corrections welcome!
The sim is flown with full parachute and a wartime Sutton Harness, so the correct seat was an early stipulation to the rebuild.
The seat Ross has built is a marvel…and so much more-so than most people will ever realise. It is built from the original drawings and is actually "time sensitive". I'll explain….
The project is being constructed as at the date that K9817, the 31st production Spitfire, was sent to the Photo Recon Unit. (PRU) This is late September – Early October 1940.
This is where nearly 35 years of Spitfire research comes in handy! She has incorporated all of the Modification Releases likely to have been implemented by that date.
With the seat, this is a "necessity is the mother of invention" mix.
So the seat is built as having been first made in October 1938...as a pretty much blank, bent piece of aluminium. Then, at later date, it has had the double riveted stiffener added across the rear of the seatback and the side hole cut in the starboard flank to reroute the lapbelt away from the seat raising mechanism.
It has not had the "extra" hole cut in the back (originally as a handle and MUCH later, to run the belts through).
Then it has had the brackets fitted for the seat armour introduced during the Battle of Britain but the Armour itself will have been removed to lighten the aircraft for PRU duties.
She will have the May '40 modifications made to the Sutton Harness run, to improve safety in the event of turning turtle!
The Flare Cartridge Rack... The jury is still WAY out on this one. I am inclined to leave it off, even though I have an excellent pattern for it and it looks like an interesting piece to make.
The seat will be painted all black as were some of the very early ones. It will have the leather patch put into the bulge on the port side to prevent chafing of the parachute ripcord. I need to do more research to work out exactly how this was attached.
Finally (and I am still debating with myself as to this) Edgar Brooks held the view that early seats probably did not have the back cushion fitted. I am inclined to represent K9817 as such. With a black seat it will not be particularly noticeable and it neatly avoids arguments as to the EXACT colour of the leather.
