Due to a special Airsporter S model I am building I am looking for the parts to convert a standard underlever Airsporter to a push button underlever.

I need the shorter underlever, push button catch, the cocking slide and the special shaped screw that holds the cocking slide and bracket.

Any or all of the parts would be appreciated, or even a battered/damaged/tatty Mk7 action with the right bits on, I know Knibbs has most of the bits but would like to try second hand first.

Thanks,
