VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1937-1945 1939 Chevy A Little Help

I have a friend living in Brazil and he is asking for some information about a 1939 Chevrolet Master Deluxe he's thinking of buying.
My question is that based on the information contained in the plate number that is on the right side of the body. I can not be sure about the car model.
In the plate number given: No. XEJA STYLE, BODY No. 663, 900 TRIM AND PAINT 1. The engine number is 2148943.
My question is: what car is this based on the information contained in the plate number.
This car is more than thirty years in the same family and my intention is to keep it original.
Thanks for your help.
