I have been tracking the bidding action on Adverts.ie. Judging from their selling histories it seems to be mainly amateur resellers that are interested in the speakers. Check out the tech specs on The Vintage Knob website. Everything is there except views of the back of the cabinets. I have a small 42 year old black and white photograph of the speakers in situ in Marino somewhere in an old Black Magic chocolate box in the attic.
