Sorry I've been gone at work for a month, but now I'm home and back to our great hobby.
I got these from Eric K. just as I got home. I have to admit, 2 of these turbines were about as rough as I've seen. The only ones I've seen which were worse had been stored in a bucket of chlorine for years! These required quite a bit of blasting to prep for the burnish. Even I was surprised when they were done! Thanks Eric!
