634 of the 130 Pz. Div. Panzer Lehr is finished in overall Dunkelgelb with an overspray of Olivegrun. The red and white shield marking belonged to the CO, Prince Schoenburg-Waldenburg, who was killed in action on June 11th, 1944 in Normandy. The battalion displayed this marking as a memorial to the end of the war. It also appears on the rear of the turret schurzen, to the upper right of the tactical numbers. The divisional symbol was a white script "L". Many tanks also carried company numbers next to a small white rhomboid outline on the front and rear hulls. (I have a photo of this if you want it.)
Das Reich and HJ divisions were among the last SS units to continue to use divisional markings. A photo of a Pz. IV ausf J knocked out near ST. Lo shows a probably yellow Kampfrune on the far left rear plate, just right of the antenna mount. This could also be found on the hull front next to the driver's vision port. And yes, that is Zimmerit on the turret schurzen as well.
