"Perhaps there is a universal, absolute truth. Perhaps it justifies every question. But that's beyond the reach of these small hands." - Yang Wen-li
As the Second World War progressed, the Soviets were fielding better and better tanks. The Finnish Army, on the other hand, had to make do with a large number of captured tanks, which were for the most part lightly armored and armed.
The Finns decided to redesign the BT-7 Model 1937 tank. They constructed a new turret and armed it with British-made 114.3 mm howitzers that had been supplied by the British during the Winter War (Q.F. 4,5 inch howitzer Mark II, also known as 114 Psv.H/18 in Finland). Eighteen BT-42 were built and these were pressed into service in 1943.

First class disaster. Ruined the BT-7s main advantage of mobility, and the new gun was completely ineffective against enemy tanks.
