Talk:Vickers Tank Periscope MK.IV

Move
Please move the article to Gundlach periscope, as this is the real name of the instrument. — Preceding unsigned comment added by 178.36.174.230 (talk) 15:03, 18 February 2012 (UTC)
 * Was it ever called the Gundlach periscope? I can see an argument for having a redirect from Gundlach Peryskop obrotowy and using that as a link on the Polish tank articles, but it seems doubtful that it kept Gundlach's name in English. Andy Dingley (talk) 10:53, 10 March 2015 (UTC)
 * Agreed, though I'm confused by the Mk. IV in the Vickers name. The periscope saw significant development in Britain, running from Mark 1 through to Mark 12.  Both US and Russian/Soviet usage is based on the British development of the design, albeit at different stages of that development.  Lkchild (talk) 22:58, 26 March 2017 (UTC)

Axis use?
An IP editor has recently challenged and removed the unsourced claim that this periscope was used in Axis tanks.

The claim is unsourced. It looks shaky too. It's worded as both "from 1940" and "until 1941", which is unclear. It talks about the Tiger, which is a couple of years later. I certainly can't think of a German AFV with rotating periscopes like this.

If we define "Gundlach periscope" as being any AFV periscope with the reverse-viewing prism, then that also implies a rotating periscope and one not in the driver's roof, only able to stare back at the turret mantlet. German tanks favoured all-round cupolas for the commander and didn't need this. I can't think of any example using this type of periscope. Andy Dingley (talk) 11:04, 10 March 2015 (UTC)
