Throwback Thursday: WWI POW’s intricate chassis model rediscovered


In 1917, we covered a ‘most ingenious’ working 1/10-scale model built by a captured British officer from scrap metals. A century later, it has been rediscovered

There aren’t many cars in existence today that were built a century ago.

Yet, incredibly, Autocar was last week informed that a car we had written about on 29 December 1917 has survived – and remains, unrestored, in perfect condition.

Almost as unbelievably, this is not a Vauxhall Velox or a Morris Oxford, but a “most ingeniously made model of a chassis which in full size would be of about 100hp, and was made from any odd bits of metal upon which the constructor, a British officer now a prisoner of war in Germany, could lay his hands in the prison camp where he is confined at.”

This officer was Colonel John HT Icke. Born in 1888 in colonial South Africa, he moved to the UK in 1901 and, at the outbreak of the Great War, joined the South Lancashire Regiment. He was captured by the Germans very early on, having been a member of the original British Expeditionary Force, which was sent to the Western Front in France in 1914.

In 1917, he was able to get hold of an ‘itinerant photographer’, as per our original article, and sent the photographs and information back to a friend of his in Britain.

“In view of the fact that all but two parts are made to operate, it is not difficult to imagine that many hundreds of hours of patient and expert application have been necessary to finish this model,” Autocar said.

“As the photographs show, it is no caricature of a chassis, but a scale miniature. In fact, if the illustrations were shown as an actually full-sized chassis, they would probably be accepted as such without question.”

Icke’s letter to his friend read: «The scale of the model, which does not represent any known make, is one-tenth.

“Every detail is as nearly as possible to scale and, with the exception of the magneto and carburetter, every part works. The material is principally ‘biscuit box’ of every different gauges. Tubular pieces, as well as the cylinders and the pistons, were made by rolling thin tin round a mandrel and then soldering the joints.

“The brass parts were made of the contact strips of old dry batteries from a pocket flash lamp. The gearing was made of an old brass hinge dug up in the garden; this was the first piece of thick metal I had, and previously I had to solder bits of the thin stuff together till I got the thickness I wanted. The teeth of the gear wheels were made by filing.

“Practically all parts had to be built up; so far as I can remember, there are about 1700 separate pieces of metal – that is, they were originally separate. All the principal parts ‘take down’, the attachments being eyes and pins, as I had no screws or anything of that kind.

“The engine has four cylinders, 9/16in bore by 3/4in stroke, and is made to work as a compressed air motor; the valves are in the cylinder head at an angle of 45deg and are worked by rockers from the camshaft running along the top of the cylinders.

“The clutch is of the inverted cone type, and there is a flexible joint between the clutch and the gearbox. The latter gives three speeds and reverse, direct on top, with a gate change. The engine and gearbox are carried on a subframe. There is one universal joint behind the gearbox, and the propeller-shaft casing takes the drive and torque. The differential and bevel gearing can be removed without taking down the axle.”

“The back springs are of the cantilever type. Both brakes work direct on the back wheels and are of the expanding type. The wheels are detachable and interchangeable. The tyres are made of cork covered with canvas, and the non-skid bands are bits of a rubber tennis-racket grip.”

The conditions in German prisoner of war camps varied from bearable to brutal, depending on location and on rank; being an officer, Icke would have been treated less harshly.

Icke was released at the end of the war and continued to serve in the army until his retirement. He died in 1964, aged 76.

His model then passed into the hands of the uncle of its current owner. An enthusiast of the Frazer-Nash marque, he ran a business rebuilding the cars and used to race them, and kept the model in storage.

Today, the model still works completely, including the shafts, conrods, clutch and gears.

The engineer who contacted us about the model, Mark Kallenberg, says: “Everything moves and works, and I am amazed at the quality, detail and ingenuity of the model, especially given that Colonel Icke had so few resources available to him.”

The model is currently believed to be worth as much as £3500.
