While I was studying in England in 2002, I purchased a pair of black
spectacles called "TIM" from Vision Express UK, Arndale branch in
Manchester (http://www.visionexpress.co.uk), which belongs to
GrandVision group (www.grandvision.com). I contacted them recently to
see whether I could purchase some more frames of the same kind,
however they told me they have run out of stock.

Is there a way to identify the manufacturer of the frame (it could be
a company in China/Taiwan)? It's a black frame, called "TIM", with no
manufacturer details printed on it, and it was provided to Vision
Express UK by the same parent company, GrandVision. I'm looking for
the manufacturer's details, or anyone else who can provide me with the
same frame (such as an optical shop).
