Yes they used the original case/glass of my Amp gauge. The internals for the gauge are all VDO. I also had him redo my temp gauge with all VDO internals and sending unit. They are both very accurate but you can’t tell they are not original.
By the way the Veglia voltage was copied from a later Maserati Bora which use the same gauges as the Pantera except the Pantera never had a voltage gauge like the Bora did.
Here’s another picture without the camera flash.
