Prototype? Prototype? That's mark iv, I'll have you know!!!!
Seriously, it could take me ages to make it look more like the fashionable ones from Carter etc. but I would gain nothing from that. It works as intended and the earlier versions did give results that were as good as the Loesch I have.
This is better than the earlier versions so I am hoping that it will shoot at least equally well. I have no doubt that the week link in my chain is the operator. A hooter shooter would give a true picture of the accuracy of the release but without one I'm going to have to improve this operator; might make me shoot better. Perhaps I will call it a training aid? "This release aid encourages the user to shoot higher scores." After all the work, it would seem silly to shoot lower scores with it. That should keep me on my toes.
