Hi Rod,
Just a guess, but I would say these are from a projector or some other thing and would be worthless as a refractor. Many things like this have been sold on Eb@y and other places and most all of them were totally useless.

I doubt very much that these objectives have any unusual color correction but even it they did they would have mucho false color... Consider what one sees in a 6 inch F/8 achromat and then consider that the actual objective is F/1.25...
