We're not debating the potential effectiveness of Germany's V weapons. We're debating your, rather peculiar belief that a trained crew could not load a 150 mm gun in 12 seconds.

Sorry about that.

Looks like a tank periscope, perhaps the Vickers mk4?

Yep, Vickers MK. IV

Any guesses for the "light bulbs" I posted earlier?

Nope. Perhaps vacuum tubes of some sort?

Actually, that is only partly correct - that is the British name for their version.  Its actually called the Gundlach Periscope.  I saw Fury on Sunday and saw all the guys in the Sherman using it. A simple but effective tool for all WWII tanks.

From Wiki -
The Gundlach Periscope, usually known under its British designation as Vickers Tank Periscope MK.IV, was a revolutionary invention by Polish engineer Rudolf Gundlach, manufactured for Polish 7TP tanks since end of 1935 and patented in 1936 as Gundlach Peryskop obrotowy. It was the first device to allow the tank commander to have a 360-degree view from his turret with a single periscope. By rotating the periscope and allowing the tank commander to look backwards through the second eyepiece, he no longer had to change position to look behind the turret. Early tanks had small turrets and fixed seating, without an independently rotating cupola, and so the commander wasn't easily able to move himself to another rear-facing periscope.

The design was first used in the Polish 7TP light tank. Shortly before the war it was given to the British and was used in almost all tanks of WWII, including the British Crusader, Churchill, Valentine, and Cromwell and the American Sherman. After the German and Soviet attack and fall Poland in 1939 it was copied entirely from captured 7TP and TKS Polish tanks and used in all 1940 and later tanks of the Germany (including the Tiger) and later by USSR (including the T-34 and T-70).

As a part of Polish-British pre-war military cooperation, the patent was sold for a penny (actually 1 Polish Zloty) to Vickers-Armstrong. It was produced as the Vickers Tank Periscope MK.IV (pictured), and built into all British tanks (Crusader, Churchill, Valentine, Cromwell). After the fall of Poland, Germany, USSR and Romania captured some equipment, allowing them to copy the invention. In USSR the Gundlach periscope was known as MK-4 (harking to the British designation, as Russian sources openly confirm that it was copied from samples acquired with British-supplied tanks) and implemented in all tanks (including the T-34 and T-70). All Axis tanks and APC (including tanks of Italy, Romania, Hungary, Finland and Japan) were equipped or retro-fitted with this periscope till 1941. Later technology was transferred to USA and as a periscope M6 implemented in all US tanks (M3/M5 Stuart, M4 Sherman and others). At the end of WWII this technology was adopted throughout the world and used basically unchanged for almost 50 years, until it was replaced by electronic devices.

Ok, but I'm pretty sure the one in the picture you posted is the Vickers version, not the Polish original. If you took the picture from wikipedia it even says so in the text you quoted: "It was produced as the Vickers Tank Periscope MK.IV (pictured)". Pretty cool, and telling of how brilliant it was, that it was used by just about everybody in WWII in one version or another.

Yeah, that's the Vicker's version. If you look closely at it, you can see how the secondary mirror pulls down for viewing the rear 180 degree arc. This thing was so common that you could probably scavenge a compatible spare from enemy tanks.

Funny that the british expected the Home Guard to confront German Paratroopers with this gadget.  :uhoh
