... Also, just because it was used later doesn't make it a good piece of equipment. The Israeli Air Force used notoriously poor quality Bf-109 fighters from Czechoslovakia made with leftover parts and surplus bomber engines because they couldn't get weapons anywhere else.

Czechs supplied the new state of Israel with plenty of (German pattern) small arms and ammunition. Immediately after the war, thousands are just laying around Europe and could be hauled away for the price of scrap iron. The key to securing spare parts is to buy as many as possible and canabalise them for spare parts. eventually, you would need new-production rubber hoses, filters, spark plugs, filters, etc.
Sadly, the new-production (Czech-made) ammunition was crap. During 1945, a Canadian Artillery officer reported that much of the Czech-made artillery ammo fired at him were duds. Israel received the same quality of ammo. I recently test-fired a variety of Czech 7.92 long ammo. Proof marks included the Star of David and 1949. Half of the primers failed to ignite.
Also consider an arms-race between Third World countries. In 1945, Germany had more lethal small arms and tank guns.
If a Third World army wanted to out-shoot the Sherman's used by their neighbors, they could try to buy Panthers with long-barrel 75 mm guns. During the Cold War, a variety of nations up-gunned old Sherman's. Whether they chose to drive the Panthers, or install those long guns in Sherman turrets depended upon the supply of Panther automotive spare parts. Maybe they could talk a Czech factory into making some new Panther tracks with the old German tooling.
