OK this is an odd one; I'm looking for a specialised camera tool that can be used for unscrewing the retaining ring around a TLR lens. Something that looks like this... I've found them online but at a prohibitively expensive price; same goes for Ebay. In the various camera and tool stores I tried no-one even had a clue that such a tool existed. Unfortunately I don't have the skills to make such a tool myself (a simple flat bit of metal won't do it, as that would scratch the lens). So basically what I'm wondering is if anyone has such a tool (or one that would do the same job) that they would be willing to sell and if necessary ship to the UK. If not, does anyone in the UK have one that they wouldn't mind lending me? Thanks in advance for any offers or advice.
