I need three parts for a broken Horizon S3pro urgently.

1. hook to take up camera-strap
2. camera-cover backside.

MOST IMPORTANT PART
3. L-shaped drum-stopper. Most important(identical to the ones in ho 202 maybe also horizont). maybe better with a shockabsorber

Wish
4. Pistol-grip(is different from horizon 202s)
5. New leather case-rebirth of the old horizont case where grip can stay attached. ebay offers.
Thanks a lot

I know how to adjust, only the regulator i dont know yet. will open it.
cannot get slow-speed although i know how it must work.
