Haenel modell 302

Hello,
A quick question for the airgun experts,
I was given a Haenel 302 for christmas in 1967 .
The mainspring has just been replaced and the gun was tested with a chrono and is putting up 7ft/lbs,would this be about right?
I remember my pals BSA meteor was always the more powerful of the two guns.
The gun is still in good order woodwork and bluing etc.
thanks in advance
Keith.
