Altec A7 What to do

Hello all, a Friend of mine has had Altec Lansing A7's sitting in his basement for several years, just couldn't put them in his current room setting. Many may know that I've been building for about 35 years. I built him a set of MTM's and delivered them for Christmas. He was thrilled. Well, today, he dropped off a pair of A7's and said they're yours. I sat them up and listened, thoroughly looked them over, looked up crossover design (500hz model) and now need to decide what to do with them. I have a decent size living room, but these are still huge. They do a lot of things right, but just aren't as refined as my current speakers. So, I've decided to sell them. I'm in no hurry to do so, but I know that I won't keep these forever. So, are these more desirable to sell as is... stock, upgrade parts in the crossover and sell them, redesign and trick out the crossover, cleanup, sand, minor fill and painting cabinets or some combination of the above. I have no doubt that a complete crossover redo, a bit of cabinet bracing and a good refinish and these babies would be incredible. The problem is... will people that don't know me accept or trust just how good they are? That being the case I'm looking for some advice. Please tell me how you would handle it in my shoes. Tim
