I'm gettin silly with a modernized M4 Sherman. And not just the M50 the Israelis had.

The silliest one I can think of is the M4A1 Multibank-Shermans sent to the UK, turned into the Firefly-meme (small turret), resold to argentina as M4A1E6s (76mm crammed into the turret), and then someone got the bright idea to wedge the French 105mm guns from an AMX-13 into it because that worked so well for the before.

They then were sold to Paraguay, where they sat on vacation as the government collapsed.

The tank was then sold to the Czech Republic.
[quote]The journey of this particular Sherman Repotenciado started in the Detroit Tank Arsenal in 1943 where it was built. After its construction, it would be shipped to the United Kingdom and converted to a Sherman Firefly. Then, the Sherman would go to Belgium before being sold to Argentina in 1947. In Argentina it would receive the registration EA 03055 and later be converted to a Sherman Repotenciado in 1977. After the Repotenciados were phased out, an Argentinian dealer would acquire this particular vehicle. It was later bought by the KVH 16th Armored Division CZ and transported to the Czechia in 2018 where it would be reconverted to the original M4A4 variant and continue its service as a reenactment tank[/quote]

There's also the Yugoslav 122mm gun Sherman.


And then there was the TAM... a Marder 1 hull pretending to be a Leopard 1 [i]really hard[/i].
