That's what they told me - they're all made by Pressac, all the same boxes, only difference being either embossed or printed OR logos. But they hadn't, at the time anyway, got any branded ones without the surge suppressor. I don't know if the situation has changed but I do wonder if anyone has yet come across an OR branded box in the wild that's missing that component. They didn't elaborate too much on the info they said they had from BT regarding the rationale behind removing it. Seems interesting that nobody else seems to know about it...
