Wamadet presses were made by my old mate John Ellis in Barsnstaple in the seventies and eighties. In his free time he was busy making a jet powered helicopter from scratch with jet ducts on the rotor tips. I don't believe he ever finished that one. I would think he'd be in his eighties by now.

I still have a practice hand grenade which fired 38 or 12bore blanks with a pneumatic timer. Very clever but rather overcomplicated.

I still have and use a couple of his presses from the eighties which are very sturdy solid steel structures which will last a lifetime or two. I even have a swaging set to fit on the press which makes 38 wadcutters from lead wire.

He deliberately made his loading stuff very simple and soldier proof so I wouldn't have thought you'd need instructions to get it working Tac.
