If they can't do anything with it, ask to get the old lens back if you have that option. Wolfgang over at astro-foren demonstrated how to repair an objective from that era by disassembling it and rearranging the spacers. A number of objectives at that time were sent out with good glass but incorrect spacing resulting in strong SA. If your old lens had an extrafocal pattern showing dull central rings with a bright outer ring this may have been part of the problem.
I would have liked to get my old lens back to have a play but it wasn't offered. WO did give me a very good upgrade deal though.
