Yes, this is an Egyptian tank. Here's some information from Maquette - the kit producer :
"Some Egyptian T-34-85 were modernizations for armament strengthening on the eve of war 1973. Egyptian have managed to mount on it a Soviet 100 mm BS-3 field gun. The turret sides and bottom parts were standard, but head and rear are removed and replaced of primitive and rather bulky superstructure by light armor sheets.
