If you have a good core, have a local person do the work. You can get better quality for a lower price and no shipping.
I started opening, beginning with the small fins, and was disappointed with the insides of the fins. I let it go hoping the larger pieces would look better. As I continued to unwrap each piece, my disappointment only grew. I absolutely would not buy these if I were starting over. You have no idea what your luck will be. The insides of the fins were not polished and the pitting is so bad I will have to fill with a high-build primer/paint to clean these up. Don’t do it.
