Yes, my long-term memory is sometimes OK 
I'll merge the two threads in a minute...
Ok - it seems that we have a pair of boxes with (hopefully!) OK woofers, but no tweeters, and perhaps no crossovers?
We assume the woofers are OK, but as I mentioned on that other thread, the voice-coil gap is open to the elements in that design, so foreign debris can find its way in. With the tweeters removed, this risk is much greater. Scraps of wire wool are deadly to most loudspeakers.
Looking at this from my "outsider" perspective, I'd be reluctant to take these on. These were "decent for the price" in their day, but eBay is full of similarly good models for less money that a repair would cost. And if that repair involves tweeters bought second-hand from eBay, I'd be worried. If they work when they turn up, how do you know they've not been thrashed? Most tweeters use ferrofluid for cooling and damping, but in many models, this gradually dries up and changes the way they sound. Without the means to measure the acoustic output, how can you be sure the replacement tweeters are working correctly? And if there's any doubt about their performance, it'll be you that has to deal with the eBay seller, and potentially take a financial risk in the process. And how about these missing crossovers? I see there's one (not a pair) on eBay for £50 BIN.
For perspective, a couple of years back, the person I share my office with bought a mint pair of Q15.2s from a local charity shop for £15. In fact, as it was a charity shop, he gave them £30! He already had a pair of Q35s (still has), and likes them. But, having just asked him, there's no way he's consider spending anything like £125 on a repair. From a quick look on eBay, working pairs of complete speakers only fetch around £50 + postage. I'd advise your customer to pick up another pair that way. Or, buy him another pair and charge him commission.
Anyway, that's my gloomy "worst-case" view. These are pretty ordinary units. It's not like we're discussing the BBC LS3/5A or similar
