I posted this on another forum and still haven't got a definitive answer, just some more food for thought. Thought I'd get some input from the armour experts here as well. When discussing the Valentine 17 pdr SP Gun (Archer), one of the things that almost inevitably gets trotted out in the discussion is one of its purported “major design flaws”. To wit, the driver of the vehicle must vacate his seat at the time of firing due to the gun’s recoil. Given what I know of the vehicle’s planned usage, this seems an odd oversight. As usual the Internet has a variety of pages referencing this claim, mostly unsourced. Looking through my collection, these are the references I have found to the issue. From Allied Tank Destroyers by Bryan Perrett Quote: [p26] From British Infantry Tank Mk III Valentine Part 2 by Dick Taylor Quote: [p9] From Into the Vally The Valentine Tank and Derivatives 1938-1960 also by Dick Taylor Quote: [p155] The English text of Ledwoch’s Bishop/Archer (Tankpower 363) contains no reference to the issue at all. IIRC Chamberlain and Ellis are of the ‘driver must vacate his seat school” The most recent book I have that mentions the subject is the Osprey New Vanguard on the Valentine Tank by Bruce Newsome published in 2016. On page 32 is the following: Quote: Sounds logical and in line with how the SPG was intended to be used. So, before I venture sending an email off to Bovington to try and determine which version is accurate, do any of the armour experts on here have any further information that may help clarify things? All help much appreciated!
