A 70ies BluesBird wasn't called Aristocrat anymore. The Aristocrat name was only used until 1963 when it was discontinued.
Since 1968 the reissue was called BluesBird.
This specific one is a BluesBird "M-75 CS" for Chrome Hardware, Solid Body.
But it is not a 1974 one as it already has the tailpiece closer to the bridge in order to increase down pressure on the bridge. Hans wrote that was introduced around 1976, so it might be a 1976 or later one.
The headstock looks strange in the picture but that might be simply a light reflection. Otherwise all fine as it look.
