Thank you Rick and Richie!
AirscrewSome details needs to be added finally.
The lockers on the windscreen sides are the smallest PE parts of the kit. The shape looks exactly as on pictures of the original biplane, unbelievable! See both below the "C", only the manual is wrong, because each one has a different form and an individual number.

The windscreen was mounted together with the prepared (see earlier updates) Aldis sight, and this little PE glued in place.

Another topic on the ToDo list was the airscrew.
The kit contains two variants. The upper one looks exactly like as on the prototype, could only be a bit longer. The one below is more a later one, according to my reference book. So I made a wooden one of the first production batch, which this serial belongs to (the C3799 is not a kit offering). Here the raw sanding on front.

And the view from back:

The prop boss is a kit PE, but I added a middle locking, turned from brass. First wood varnish.

The final airscrew, the locking is glued and the boss is "bolted" with 0.2mm nickel silver.

Plugged to the Dolphin. Originally I wanted to paint the blades gray, but the airscrew is to nice to hide it!
The Datafile shows beautiful pictures of C3786 with a wooden airscrew. The C3803 as option of the WNW kit has a wooden airscrew. This C3799 is just between them, so I guess this painting practice was done later and not yet on the first Sopwith batch.
It is not glued yet, so any veto against my theory?

I ordered also this Lewis from Gaspatch. I had some, but not this variant. Painted with Alclads and scratch build a mount. I guess this (white) plate is to avoid to shot into the airscrew.

And glued in place.

Pitot was added and connected with 0.2mm lead lines.

And a final view!
The scratches on the Vickers was fixed with painting Alcalds with brush, other scratches fixed too. The RAF wires are metalized and the sockets of the RAF wire terminals are painted black. Finally a very light weathering was applied.

I was going through the manual again, but it seems that all parts are mounted. So after a loooong journey this build ends and the
Sopwith Dolphin is finished. What a great kit and what a project!
Thanks you all for following and your inspiring comments!
Cheers,
