If it looks like the lens element i got back from Focal point it will be as new. First class job for both polishing and coating.
Best to contact John Van Stelthen directly for pricing. http://www.focalpointlens.com/fp_intro.html
Yup, I did just that. He gave me a ballpark... but needs to see the lens for an accurate quote... The lens probably isn't worth re-coating (Meopta Mirar out of a Flexaret IIa)... but the camera is part of the family, was my first TLR and used to belong to my wife's Grandpa back in Czech... so yeah...
An note, Magnesium Fluoride can be coated with the lens cold, be if you heat the lens to 300 degrees (I think F not C) the coating will be hard. All navy ships had an shop to recoat optics until the hard coatings made recoating unnecessary.
