Developed in the early 1930s, the Vickers Commercial 6-Ton Tank was not adopted by the British Army, but was very successful for Vickers as an "export tank", purchased by a number of foreign countries and influential on several subsequent designs.  This 1934 photo shows Vickers 6-Tons in Polish service.  They are painted in the distinctive Vickers standard "Chinese" camouflage (incorrectly labeled with this photo - and illogically - as "Japanese") pattern.  Best regards, JR.

Cromwell tank

Polish Vickers 6-Ton Tank destroyed by German antitank fire, Poland, 1939.  The Vickers 6-Ton was a sturdy and reliable little tank, but it was seriously undergunned (1 3-pounder low velocity gun main armament) and not adequately armoured (13mm frontal) to resist even the much-maligned German 47 mm. "door knocker" antitank gun.  This example seems to have had its door comprehensively knocked.  Previous captioner records that the driver was killed when this tank was knocked out.  No surprise; if the whole crew had been killed, I would not be surprised.

Poland was one of those 6-Ton purchasers that used it as the basis for a successor tank, built under license.  This was the 7TP Light Tank, with increased frontal armour (17mm as compared with 14mm) and a considerably superior main armament (37mm high velocity cannon).  They did not fare much better against the German panzers and antitank guns - a matter of organization as well as technology.  Best regards, JR.
