Decent, but not show quality. Removed from a stock 76 GT550. 10mm thread. Both mirrors have a slight caved in area around the stem. I am told these can be fixed, but I don't have any interest. Excellent scratch free glass. There is one small scratch near the mirror edge. Looks huge in the photo as it was ultra close-up. Have to look hard to find it.
I know these are rare and I know they command mega-bucks. However, though nice, they are not pristine. so I will price them as such. $50 + actual shipping. Strange reflections from overhead canopy.
I was born with nothing and still have most of it left.
