I have a question about the forerunner of the Caernarvon & Conqueror tanks, the FV201.
From what I can find online, the Caernarvon evolved from the FV201 and started out as an effort to develop an "universal tank" armed with a 20-pounder.
What I would like to know is if the "'universal tank' armed with a 20-pounder" description also extends to the FV201- I know that the FV201 was tested with a 17-pounder; but is that the intended specification of the FV201 programme, or is it merely a result of testing the hull when there was no 20-pounder turret that could be spared?
Thanks in advance.
