Only two were re-sparred and 1717 was sold to the Stanger Museum but when last seen was in a very poor state minus wings and has most likely been scrapped by now.

Thanks,

Flypast article hinted that three were re-sparred?? Thank you for your update.

Anyone know what happened to the third Mk3 Shack which was re-sparred? 1717??

Is this a modified passenger cabin repeater panel from perhaps an aeroplane of the empire routes of the twenties/thirties?

Altitude, speed, time and I believe the G&T contents gauge is missing from the group?

(better tell the Iranians that it’s DEPLETED urainum, not enriched – before they start stripping down their aircraft ! :diablo: )

Still not very nice stuff when burnt, vapourised or rendered into fine dust. Unfortunately just what happens to munitions when they hit their targets.

There is a lot of suspicion falling on DU as a major culprit in what we know as Gulf War Syndrome. Not good for the lungs…

I understand that “cellulose” is an abreviation of the base component “nitrocellulose” WRT to paint systems. The enamel description may just be a generic reference to a hard glossy coating system whether clear or pigmented.

“In 1923, E.I. DuPont De Nemours developed nitrocellulose lacquer systems, which offered many color choices and easier application using spray guns. However, lacquer systems required spray application of 3-4 coats of paint to achieve the desired properties. Lacquers also by their very nature have poor resistance to certain chemical solvents. Repeated exposures to gasoline spills could stain and damage lacquer finishes. In fact, in the 1960’s some cars had their gas tank filler located under the license plate to avoid spilling gasoline on the lacquer paint. Nitrocellulose lacquers were used on some passenger cars until about 1957, when solution acrylic lacquers were introduced. Acrylic lacquers offered much improved durability and a wider range of bright, pleasing colors – especially metallics.”

“Nitrocellulose Lacquer: in the 1920’s, several paint manufacturers were involved in the development of nitrocellulose lacquers. This paint had rapid drying and low viscosity properties, and was applied with air pressure through a spray gun leaving a hard dry finish in approximately one hour. When rubbed, polished, and waxed, it far surpassed in durability and appearance the qualities of the Japanese lacquers.

Synthetic Enamel: In the mid 1930’s, a new and completely different type of paint was developed, the alkyd or synthetic enamels. It proved to have superior qualities in film strength, adhesion, luster, flexibility and durability over all previous paints. The resin base was developed from the reaction between phthalic anhydride and glycerin, with gums, oils and plasticizers added during the manufacturing process a drying oil such as linseed, a polyhydric alcohol, such as glycerine, and a dibasic acid, such as Phthalic Anhydride. It dries by solvent evaporation, like the lacquer paints, but the resin remains soft and sticky when no solvents are present. It cures to a hard finish by absorption of oxygen from the air. The curing process can be accelerated by heat, and several methods of baking enamel were developed. Unlike lacquer, when dry, it needs no polishing to produce a high luster finish.”
