I think you are being a bit optimistic on your price expectations for a rough set of 108s. Judging by the two tone nature of these, they have already been refurbished at least once before so the bolt hole threads in the outer are going to be a nightmare for the next refurb, unless they were all helicoiled first time around.
The going rate is normally around £100 for a set in need of refurbishment....
Good luck!
