Looks like it probably is. However not a perfect restoration by any stretch. Windshield, wipers, mirror, bumper, drivers seat, all look incorrect to me. However the grill and front axle look correct, probably the frame is right, but need more pictures and you will get responses from others who are better at spotting things than myself.
Look for the metal tag on the inside of the left front frame rail. If it says MB...... that's the best id. Often they are missing, so don't worry if it is not there. Also read the data plates on the glove box door if it has one.
