I replied to your previous post but didn't get any answer.
I keep turning up Aigner/Felder items in the workshop that may interest you, for example I've got one of the Aigner devices for safely ripping thin sections of timber, it's like a sub fence that transports the workpiece through the saw while keeping your hands well clear.
If you can give some idea of what you're looking for I'll invest the time to make a more detailed response.
