English heavy tank Mk.V experimental “flexible” tracks from a certain designer by the name of Johnson, while ispiti in mucky somewhere near Dollis hill in North-West London.

It is unknown how successfully passed the test (we only know that the tank is equipped with a more powerful 225-horsepower engine could accelerate to a mind-blowing 20 miles per hour), but afterwards the tank was taken to Bovington, where after some time was dismantled.

British GD (General Duty) Mask

@helykk asked earlier for some info on the GD, so here goes.

GD Mask

The General Duty was produced by multiple British companies, including Avon and Seibe Gorman, from roughly 1939 onwards. The “General Duty” name is indicative that it was meant for CD vital personnel, and as such the mask is much higher quality than the GC (General Civilian) mask issued to common civilians (shown below)

The GD mask facepiece was heavily based off of the Mk. V GSR (General Service Respirator) in use by the British military before and after the war.

While the facepiece was essentially the same, removing the metal plate on the front of the mask meant that there would be no inhale or exhale valves, greatly shortening mask lifespan. As such, a large inhale valve was added inside the mask, and a flapper valve (affixed by a metal triangle) was added directly above the filter to greatly improve ergonomics.

Since GD masks were often issued to telephone operators, a rubber boss was added to the lower left cheek of the mask (also seen on the Mk. V) so that a microphone could be added.

After the war, GD masks saw usage in industrial situations, often having their filters replaced with specialized ones. Examples have been found with filters dating from the early 1970′s. The microphone plug is not present on some later examples, implying that they were made post war.
