What can we conclude from the mere fact that there has been a Gübelin cataloge picturing an Ipsovox E858 Parking?
Right: that there has been a Gübelin cataloge picturing an Ipsovox E858 Parking.
Nothing more, nothing less.
Not even that there has been a Gübelin Ipsovox E858 Parking.
Ceci n'est pas une pipe!

What can we conclude from the additional fact that there has been a Gübelin Ipsovox E858 Parking - assuming that it is authentic?
Right: that there has been a Gübelin Ipsovox E858 Parking.
3)
Can we conclude from these two given facts that JLC themselves issued a E858 Parking, i.e. that Clavi's JLC E858 is authentic?
No.
Please do not get me wrong: I am not claiming that Clavi's JLC E858 Parking is not authentic. I am just noting that there has not been presented sufficient evidence (in this thread) that it is.
Marv, what you describe as learning is essentially finding facts that amount to premises needed to draw the right conclusions. I am really interested to know whether these will be found or not.
