It seems 'false pm' requires a 'horse' in order to become 'true pm'. James Cox 'true pm' was a 'horse' powering his clock 'cart'.
I expect Bessler's 'true pm' will be a 'horse' powering his wheel 'cart'. We clearly need a 'horse'. We already have the 'cart'.

I went and read about James Cox self-winding clock that used mercury and barometric pressure. If the clock was that sensitive that it used changes in barometric pressure, then perhaps would a bellows create an artificial pressure change sufficient enough to be the horse?
I notice the little mechanisms at the top and bottom seem similar to the hammer toys of MT138. Despite all of this, I still don't see how a self-winding clock-style mechanism could power anything. Was Bessler using some kind of a rube-goldberg device that started with one microscopically small and hidden energy source to gradually build up to one larger OU producer?
I think that some of us at least recognise that there must be a duality of separate 'horse and cart' structures to arrive at the fabled true PM wheel arrangement. And experience and/or logic, plus analysis of physics and math tells us that the classical gravity wheel PM attempt is both a false PM 'hope' and the 'cart' in this metaphor for true PM.
And so we look for 'power sources' to be the horse. And if inventive enough and diligent enough in researching the past we can come up with some seemingly plausible possibilities. Many like me eventually discount ambient diurnal pressure and temperature changes captured and harnessed to wind a spring as just not having sufficient power density to replicate Bessler's wheels performances. The green horse is a bust.
So we look for other alternatives available in his time or earlier. Bill came up with an ingenious heat engine design based on a Stirling Engine principle which if used by Bessler was well before they were actually invented in Scotland. It purportedly has the energy density required, but did need periodic fuel replenishment. A good strong brown horse to literally pull the cart around.
And so the debate shifts from the requirement for a horse in this metaphor to would some horse solutions be true PM and others not ? Well there is evidence that Drebbel's and later Cox's self-sustaining machines were considered true PM at the time. Tho Bessler nor Wagner IIRC makes any mention of their position on it, tho you think it would have come up if Wagner suspected it. And the problem of harnessing enough energy density inside a volume of wheel is still unresolved and a barrier. No apparent way forward to progress this position.
I admit I can't bring myself to accept that a hidden calorific fuel supply needing replenishment would constitute true PM in any age or time, ingeniously disguised and used as it might be. In my mind that would be a step to far for Bessler's and Karl's credibility and integrity stock, with repercussions.
So I am left having to decide what colour is this horse of horses ? I know that it can pull many carts, or can it ?
So I decide to take another route, approach the problem from a different angle or perspective. Suspend all preconceptions about conservative gravity fields and try to not take all things at face value but instead apply logic where I can. This means that I do not just accept that the cart is just the cart dragging behind the horse. The horse can move along and carry a load on its back just fine without the cart. The metaphor can only get us so far. So maybe the cart has another equally important purpose to true PM. What could that be ? Why are carts interchanageable and how does that relate to the purpose of the cart ?
And when all said and done it distills to this. That in order for a gravity only machine/engine to work as described by Bessler and Karl etc then the wheel's (made up of horse and cart) CoM must be consistently OOB, even as Bessler described it to be. Since we know that the classic cart-wheel (excuse the pun) can't ever fulfill that requirement then we must look elsewhere and at the role of the big black horse also firmly in the frame !
