If not, then it would be plausible that the hideous gas welds in those pictures would be period correct for a coach builder for that time period, and likely authentic, though not by GM.
Some high end coachbuilders aren't exactly that fussy either Carl,I had reason to remove a rear glass from a Hooper bodied Rolls Royce recently,it's amazing what can be hidden behind acres of walnut veneer and mohair.
It was a stretch wheelbase and had some seriously rough looking welds.
The actual glass was held in with RTV sealant,small angle brackets and self tapping screws and we had no reason to believe it had been removed previously.
P.S. Thanks for everyones input.
