I have owned these vintage Wharfedale 506 speakers from new. I bought them in 1986 and they have been inside a house during their entire life - never stored in a loft or garage.
They are in very good working condition, but with a couple of small cosmetic blemishes - see photos.
There are a couple of rub marks on the side of one of the cabinets
One of the fabric covers has some light spots on it.
