Ferdinand VII 8 Reales Cataluã±a C/S Y2 Manilla+chops Fake?

I think that one was briefly discussed sometime ago, but as it's still on ebay, and as someone else is telling me he things it is genuine ...
A nice coin to study :)

Here are my thought about it :

* The counterstamp was applied with too much force on the coin, usually this was done with a hammer, not with a power driven tool (with such power)
* Proper mixed silver shouldn't break like that
* The chinese countermarks seems to have been recently applied as well (you can see no circulation wear on them, some even show the bare metal flashing under light)
* What was a cataluña coin doing there ? Those were very scarce even in spain ... moreover the coin is very worn, I'm not a specialist of those counterstamp - but is that possible between the date of minting of the coin and the date of the counterstamp ? (I collect spanish coins up to Ferdinand VII)
* The second "foreign" conterstamp look odd ... check out the facebook group, we have a nice gallery of fake counterstamps there.
* And to finish, the look of the chinese countermarks don't look that familiar (either their design, their position, and so on)

Here is what another specialist told me about it :
