I'll go over a period of several months' changes.
It had;
A Pz.3 turret bin.
Bolts beside the hull MG.
A cable on the left hull side.
No antenna mount on the rear wall.
Smoke launchers on the turret.
A jack was on the rear right, but this became cut off and was stored between the exhausts.
A Feifel system. The crew operated without it, but the large V duct was on the engine hatch.
Probably the later cylindrical tail-light, but I can't see this.
The hull side fenders were in a bent line, had no end plates, and had 2 different lengths.
The ends of the tow cables were toward the hull front. Because there were no S-mines, the clips were further forward than you might expect. See photo below.
The fire extinguisher was in the original position, close to the engine hatch.
Probably it had a spade on the glacis plate, but I can't see this.
The track toolbox was in a metal frame. This was converted to hold jerrycans.
The mudguards were the standard folding type before the got lost.
The mantlet had a thickened part on the left.
Rings on the holes in the glacis plate, over the tracks.
No escape hatch.
The original short hull front edges.
The engine adapter was slanted.
No S-mine equipment or attachment points.
No rectangular plate behind the driver's hatch.
No exhaust shields or attachment points.
No shaft stored on the bottom rear hull.
