ID this alternator?

My friend has his sisters '72 Charger at his shop and the alternator deal is killing him. Got two of the wrong alternators from the parts house he works for...not sure if the car ever had the correct alternator on it since his sister bought the car.

I've steered him this way to help him out... warm weather is here and she can't drive the car (georgeous '72 Charger with a mild 440/TF in brandywine paint. Very nice...)

I can't imagine where this alt. came from...yea I know Chrysler. I haven't owned a '60's Mopar since '68!
