I think it is the 5" model.  I think it was sold some time ago.

yes - looks like the 5" Pier Mounted Model 520.  The large brass gear is distinctive, and the small drive shelf on the pier differentiates it from the 6".  The 5" used the same weight drive as the 4"- the 6" had a massive weight drive.

looks like the box next to it has all the controls and clock drive links.

I'm aware of one other 5 inch Polarex in Australia...in the hands of a private owner.

Nothing definitive.  Had one input of fifteen 5 inch but suspect there are more than that out there.  I try to keep this page updated: https://www.unitronh....com/locations/.
