I bought this from the estate of a former WWII pilot. No one knew what it was and was wondering if it was for an airplane. He did have a Volkswagen dealership at one time but this is marked Made in France. Thanks

Citroen boot kit? It looks all the world like an accessory tool kit for a car - spanners, extensions, and sockets. What's in the cardboard tube? Can you give us an idea of scale?

Probably a jack.

Has a brush inside the tube.

Ok, now you really have my interest. The brush looks to be 2.5-3 in. in diameter. Is that a pull thru lanyard attached? The L-shaped spanner at the top looks like it fits the round headed lug bolts. Is that correct? What do you reckon those bolts are made of? The extension with the universal joint looks like it teams up with the cross handle and socket in the bottom half of the case. Is this so? What's in the pouch top left and the cinch sack lower left? Can we get a pic of the box end spanner?

The black rubber in the upper left hand corner is just to hold the items in the lower left corner of the box. The ball joint looking items do not fit any of the wrenches. All the tools are plastic coated; maybe to protect them from salt water? The brush is 3 1/2". The ball joints ? are not magnetic. The measure about 1 7/8" tall and one inch across. These are two of his planes. They are supposed to auction off 13 planes later.

OK, a Grumman Goose and a Republic SeaBee and a box of tools. Those lugs may be the replacement aluminum control linkage knuckle for one of the planes or maybe a door lock stud. The bag of parts looks like a collection of nuts and bolts and I recognize access panel fasteners with the wing nut tops. I'm gonna say now it is a spare part and tool kit for a seaplane.

That is a starting point. Thanks

I met a gentleman today who told me he worked at a Florida airport as a mechanic back in the 60's. When showed your pics he immediately identified that as an aircraft maintenance kit.

The L-shaped wrench with the crow foot is for tightening or loosening cylinder bolts on air-cooled engines (radial mostly and some horizontal opposed) The T-handled wrench is for reaching down behind the cylinder jugs. The wire on the socket is used to hold the nut on and/or retrieve the socket when it falls off the extension. The nuts and bolts are likely replacements for linkage pins etc. The brush is still a mystery, but he said it was likely used to clear intake, air, and exhaust ducting to remove bird nests, spider webs and such. He said it looked pretty general to him and not plane specific. The aluminum nuts are still a mystery but likely a knuckle or hatch latch post. Black rubber hole plugs are visible. The wing nut looking knobs are called Dzus Fasteners. They were used to close maintenance hatches such as fluid check and fill.

Is that Goose flyable?

Both are.

Thank you Bobster
