This is a bit of a longshot but I'll try!
I have a Fantasea UWL-09 wide wet lens - they are supplied with two adapters in the box: Type A and Type B (for different housings). I use the Type A with a Fantasea housing but unfortunately the screw thread has gone soft so it will no longer attach securely to the housing.
I'm hoping to find someone that has the same lens, that uses it with the Type B adapter so doesn't need their Type A. I could either buy their Type A adapter or swap my Type B that I don't need for their Type A that they don't need.
I'm mainly UK and Red Sea based but an exchange with someone in Europe could also be arranged!
Thanks a lot,
