"Quality in the Kitchen" ... any one heard of it?
This is the underpan logo of Swift Cookware, which I believe comes from Birmingham, England. Go to Amazon.co.uk and search for Swift Cookware and you'll find the current range.
Thanks for your post ChrisCrutch, because it led to me finding this cookware. Just this morning my wife said that our egg poacher was the best cookware she had. I searched the web for their logo and found your post, and recognised the bird as a swift, so searched on that and found the whole range. Then looked at the lid of the pan. ....., which said Swift!!
Hope you get notified of the post, in which case you've at last found your cookware - not cheap, but fantastic quality.
