Sony Stereo Hi-fi Speakers

My mother passed away and I have her Sony speakers in good condition for sale. I am sure that she only bought good quality items and that these speakers are not a counterfeit, but I did not keep her receipts when I emptied her home to sell it, as very upset and not thinking about the need to prove items were not counterfeit, so don't have them. I have the manuals for most of the Hi-fi kit- just not for the speakers. 
We have other hi-fi equipment such as cassette decks and tuner for sale too.
Most people either collect or if too far, use Hermes as much cheaper than GPO and you can arrange payment at your end. You can work out size and weight and book Hermes and I can have it out for them to collect once you have paid, sent me the barcode as I have to attach that once I print it off and have packed item. Has worked well.
