Thanks, Adam and SchwereP.
Getting the balance right between practicality, and delicate add-on eye-candy is what
RC AFV makers are all about, I guess.
The Schumo 'C-Hooks' might get shaken loose, for example, on a pebbly beach- or pulled away in long grass. Real JPs had retaining pins, and small chains, to keep the hooks in place.
I might go as far as retaining pins.
As a final add-on, some periscopes with simulated glass should give a bit more detail, without compromising cross-country capability.

No one wants to leave a trail of expensive 3rd party add-ons in the long grass.
Interestingly, whilst looking for
real details on
real Jagdpanthers/Panthers, I discovered that Britain commissioned the building of
nine Panthers, and
twelve Jagdpanthers, and had them shipped to the UK for testing. It's such a pity, that nearly all were scrapped eventually, along with all the captured German aircraft we had.
They were build from spares, and incomplete examples, at the factory in Hanover, which was then (1945) in the postwar British zone.
Mark Felton mentions them here (see below) The 'Heikendorf Panther' was also one of these Brits build models, it seems- along with the Panther at Bovington.
