M3 lee early production

I'm back to present a historical reconstruction of the M3 Lee. At the beginning of production, its armor was riveted, but in later production it became cast. Historically, it was only a transitional tank for the USA. Indeed, at the start of the war, the only tanks available in significant numbers were the outdated Stuarts, and the Sherman wouldn't appear until 1942. In short, it was primarily the result of improvisation. It made a good impression during its first appearance in North Africa, where its 75mm gun riddled the German Panzer IIIs with holes, as they struggled to penetrate it head-on, forcing them to regularly rely on the 88mm anti-aircraft gun, artillery, and aircraft. But it was against the Panzer IVs and other heavier German tanks that it showed its limitations and was replaced by the famous Sherman.
