Interesting replies. P&H sights on an Airsporter or Club that's something you don't see very often. Is the Airsporter a 177? What mark of Airsporter is it please? I assume it is 177 but if you don't ask you don't find out.
Thanks for I remember the Mercury in its target guise & can quite understand why its not often seen. It must have been a very small take up. Wouldn't mind having a go at making up an Airsporter with contemporary apperture sights, the only thing that puts me off is messing with a 50s Airsporter in 177 but if it could be reverted to original form without any holes etc it might appeal enough to have a go.
Also nice to hear that bell target shooting is still going on........Frank Spittle wrote a nice little book on it, a good read. I'd say its worth getting a copy if you are interested in the topic.
