Hi Brucey / Lazerbrain,
Many thanks for your offers.
Indeed Lazerbrain, the metal clip within the lens is fine, but it's the actual plastic pieces that this clips into that has broken. Therefore, I thought that I'd haver to replace the whole lens.
Brucey - shame I din't look at this post till now, as I was at Brands today and could have got this off you. I'm curious to know more about the Ring Halogen Conversion you did? I'll send you a blatmail, and at least come to some arrangement with you for now for the lens.
Cheers,
Ben
