1957 Land Rover Series 7 Short Box Pickup (Rare Barn Find)

This is a recent barn find. Was owned and driven by an elderly Idaho man until he passed away. He kept it in his barn. Told everybody it would climb trees, but will not guarantee.
Don't really know very much about these. I have never seen one before. Quite unusual. Body may be aluminum?? Have been told they are quite rare in the US, but don't know if that is true.
Told the engine is a small block Chevy engine and guessing a 283 or 350 CI, but have not verified. Has old style Corvette valve covers. It starts easy, runs good and drives well. It has a 4 speed manual transmission and it has a two stick transfer case.
Bought it because it was so ugly that it was cute. Short wheelbase. Believe all drive trainin good working order.
Not sure what the real value for it is. Book values are quite high. Sorry, but I don't know much about this vehicle. Bought is on a whim and now it needs to go to someone who will take good care of it.
After buying it, I discovered I am much to big for the cab. I am 6'2" and 250# and while I can squeeze in and drive it, it is not comfortable. This is for someone smaller.
Vehicle is located in Nampa, Idaho 83651. Willing to assist with transport internationally. Have a free and clear Idaho title to it
