This, somewhat astonishingly to me, is the seller's video for a Canadian-manufactured version of the 1943 M4A1 "Grizzly" Variant of the Sherman Medium Tank.
This version (and Shermans had lots of different power packs) is powered by the Continental-built 975ci Wright Whirlwind radial engine--originally an aircraft engine. When the driver blips the engine, as he starts it--unless it was warmed up before, he's doing it a bit of a disservice.
Also, the tracks have steel shoes with no rubber pads; look at the damage level to the pavement lol.
This M4A1 Grizzly is an adaptation of the Sherman medium tank that was built in Canada in late 1943. It is a cast-hull variant of the Sherman and is powered by a Continental-built 975ci Wright Whirlwind nine-cylinder radial engine. Additional equipment includes a Spicer five-speed manual transmission, a demilitarized 75mm main gun, a propane-fired .50 caliber replica machine gun on the turret, and a dummy .30 caliber machine gun in the forward hull. The engine is said to have been serviced during prior ownership, and work performed in preparation for sale included flushing the hydraulic system, changing the engine and transmission oil, adjusting the clutch and brakes, repairing wiring, greasing the road wheels and fittings, repairing the tachometer, and more. The olive drab exterior was also refreshed during current ownership, and the fighting compartment was stripped and refinished in white. This M4A1 is now offered on behalf of its current owner in California with a bill of sale.
On 11/29/2020, it was bid up to $480k--but this fell short of the owner's reserve price and so, it remains to be offered again.https://bringatrailer.com/listing/1943-sherman-m4a1/
