I have a 33 EAGLE 3 window sport coupe rumble. I know they were only made from beginning of production to end of FEB 33. After that the were re intoduced as a master with some small changes,one of witch was the addition of a stationary window channel between the vent and the door glass,the only way I know to tell a EAGLE from a MASTER. I have seen over all coupe #s but have not seen break down on model's. I have heard as low a # as 400 of these built but this is not confirmed, can you help?
