I just found three pics of my Ultra T401 published here on an Ebay listing item no. 161981757832. They had no watermarks suggesting that this seller has a password to the site and so is able to download the clear full-sized pics. In the listing he stated that 'This is my Ultra T401 radio.' It's not, it's mine, and sellers should take pics of their own sets to sell them on Ebay.

Hello again,

The pics have now been changed on the Ebay listing. However Ebay were made aware of the problem before they were replaced, agreed that they were from Radiomuseum and are taking action.
