I didn't have much input into the SCB ret, well more accurately not much of my input was actually implemented.
The one thing Gary did put in was the floating cross in the centre, the original SCB didn't have that and I suggested it would help to reduce some of the clutter to have a floating cross, that would also give an extra aimpoint as well. Gary didn't agree with me, but Sammie overruled him and it made it into the production models.
Webley/Logun asked me to design an HFT reticle for a new range of high quality scopes a while back. Which I did - I called it the Kite reticle, but it never saw the light of day because they went under sadly. Shame it was a really good ret
