It would be about 400 miles round trip to collect it, and it's up for £180 or offers. So by the time I consider the fuel and a day's driving I might as well take a chance and have it shipped. It wouldn't be worth paying someone to restore it, but I hope to learn the skills and do it myself.
I saw the post by
@Moko earlier today, about a similar era accordion (which prompted me to run another search on eBay) and I might well take the same approach - acquire a couple of similar instruments, and make a good one from the two.
I'd be almost happy just with it nicely polished in a display case, but if it plays well too, well that would be a definite bonus.
