Anyone with a reasonable idea of what makes a truly accurate scale model or restoration will appreciate, above all else, the value of a good period photograph. So too aficionados will recognise the tremendous value of publications like Ampersand's Allied & Axis, AFV Modeller's Duel In The Mist and the Panzerwrecks series above all others, in bringing to light not only interesting photos, but thoughtfully formatted nice and large in landscape format, so the details are far more discernable. Publishers like Concord and Osprey perhaps ought to take note!
At the beginning of Panzerwrecks 4, for example, is an excellent array of beautifully clear photos of a Jagdpanther belonging to s.Pz.Jag.Abt 559, KO'ed not far from Raamsdonk, in the Netherlands on the 1st of November 44. One of the photos is the clearest yet published showing the well known, but thus far unidentified marking on its LH front fender:
Close examination of the photo suggests it is in all probability a stylised frontal view of a Jagdpanther, just somewhat disguised by damage to the paint surface and the angle of the fender to the camera. What colours it was originally painted in are naturally open to speculation:
This marking may have also been applied to the rear left or right stowage bin, however no photos have thus far surfaced that we are aware of showing the vehicle’s rear to confirm this. Nor to the writer’s knowledge have any other vehicles been identified with this marking, but it is unlikely to have been unique to this vehicle. Given the makeup of s.H.Pz.Jg.Abt 559, with only its Stab and 1. Kompanie equipped with Jagdpanther, while its 2. and 3. Kompanien were equipped with Stug III, it is possible the insignia may have been a 1. Kompanie marking rather than divisional sign.
This further shot shows the same vehicle (tactical number unknown), post war, after it had been bulldozed into a ditch:
For the record here is a selection of other s.Pz.Jag.Abt 559 Jagdpanthers, which go to show the lack of further evidence on this insignia. This first set of shots show the well known Befehls Jagdpanther “01”, KO’ed in early September in Belgium near Joe’s Bridge, on the frontier with Holland. This JP now resides in the Imperial War Museum. No stylised JP insignia is evident on either front or rear, however this may be on account of damage to the Zimmerit/rear stowage bin:

"
Dutch researcher Marcel Zwarts’ managed to interview the former commander of s.H.Pz.Jg.Abt 559, who told him the commander of this JP, a Major Sattler, was apparently injured not by enemy fire, but from a fall as he exited this vehicle.
This next eg is also a Jagdpanther Befehlswagen KO’ed in Belgium, this time in the town of Geel and photographed on the 13th of September 1944, just prior to Operation Market-Garden. The vehicle was destroyed during a battle with the British 50th infantry Division which took place over the preceeding three days:
The dented and scorched nature makes it difficult to determine what markings it may have carried. Modellers however may care to note, apart from the charactoristic Befhels Sternantenne Fuss to the left of the rear crew hatch, visible on its deck lay two signal wire spools and at least one jerrycan.
This next example was also KO’ed in Geel and may have been a victim of Shermans belonging to the Nottinghamshire Yeomanry, which supported the 50th Infantry Divisions attack:
Again, the damage to the Zimmerit and overall quality of the side shot is not sufficient to ascertain if there were any tac numbers or Balkenkreuz applied to this eg:
This final example below was photographed just NE of Geel, on the 17th of September 1944, at the beginning of Operation Market-Garden. After The Battle's Operation Market-Garden Then & Now explains the burning DC-3 Skytrain beside it had been shot down by Flak after dropping paratroopers of the US 101st Airborne Division in the Son area of Holland. All of the crew apparently survived. This JP was actually KO’ed a week earlier in the same battle as the previous two egs. Unfortunately once again no markings are visible:
