Is this a real Testarossa mirror?

I bought a "new OEM" Testarossa mirror for my 1988, but it is not shaped exactly like my other mirror. This one has a bulge and seam inside of the hole where it attaches to the car. I also see a strange seam on the other side. The rubber boot is also a bit larger than the original or driver side.

It has the Cromodora stamping and the little tag on the underside of the mirror that look correct.

Did I get something from a different car? Is this a reproduction?

Any help would be appreciated.

Ok, think I might have figured out what I bought. Evidently there are several Ferrari part numbers for RH mirrors for the two mirror cars:

61549800 RH outside mirror - US (Until car 78847)
61574100 RH outside mirror - US (From car 78848)
For 512TR:
63065000 R.H. outside mirror for US LHD

and then what I think I have which might be for a 512TR:
63064800 Non-US outside mirror (for a RHD)

So this theoretically could fit, but its not the correct mirror. Its for a 512TR or F512M
