it' seems like to Aeroproduct blade because there is a balance cup with lead mass into the blade shank retained by balance washer stud.

HTH part number 15 7513 22 gusset

and if it is 15-7513 ? part number 15-7513 was the frame install entrance door on B17G

before machining the blade there is a raw, this 1444 matrix give the 1444 type, then in these same matrix other types as 1635,1719 could be machined. the overall shape of the blade 1444 is typical Ratier design but made by Chauvière sub contractor?

1444 were also used on Amiot 340 propeller 1635 blades were obtained from 1444 matrix I found these information in "notice de renseignement. Ecole de mécanicien de Rochefort- armée de l'Air- 1939", and Ratier propeller notes

Chauvière 1444 blades(clockwise) and 1443(counterclockwise) fitted on Ratier hub were for prop on the Bloch MB210 powered by two Gnome Rhone engines 14N. Material blade was alu alloy L2R, dia propeller 3,20m

This blade is clockwise rotating(seen from pilot) but french single engine airplanes had counterclockwise propeller. May be a propeller of twin engined as MB 174/175 or other

it's interesting to see, under the fuselage, the shell and link retriever doors instead the ejection chute. On this airplane, these guns don't eject shells out of airplane but stowe them in the inboard leading edge.

air starter diagram on NiD 62 first, if neded,, inflate the air cylinder by hand pump open the cock (H) and check air pressure for start, magneto 1 & 2 ON, , push the mushroom valve (I) during 2 secondes then turn the starter magneto until engine run. shut the starter cock when air...

if the pressure is enough, there is no need helper to start engine. for this reason. later, Viet add a hand pump build in to the starter and a driven pump.

Viet starter had a pump build in starter body to inflate a air cylinder, On Nid, the mechanic use a bicycle pump type(stowed behind the pilot) to inflate the cylinder which allow 6 starting when the pressure is 10kg. May be was a first model of Viet starter?

The starter was a air system which injected air in cylinders through a carburetor and distributor. The pressure push the piston and the engine turn, a specific magneto(starting magneto) allow the run of engine. now it is possible to start engine by driven the propeller but not by crank(there...

The four lines on tail of AD Skyraider was to adjust the approach light located on leading edge of port wing. An observer stay at 15 feet forward of approach light and with eye level adjusted to sight over wing at - 2° line, then adjust approach light so that observer sees center of amber...

at the root we can see the blade clamp hinge which maintain the two halves of split sleeve...it's a Curtiss duralumin blade, not for Mosquito prop two last digit are missing, so I wrote "89303-2." followed by dots

The blade root gear is typicaclly Curtiss prop, the blade may be DWG 89303 - 2... fitted on Curtiss hub of P51A, P 40C & C, E...,N
