Feeder arm seat clamp

Hi Folks,

Does anyone have a contact number, email for the company that makes these
clamps that fit to the leg of your fishing seat so you can clamp in a
feeder arm or whatever - they advertised fairly frequently in the angling
press but I've no old copies to have a look at.

As is the way of things I cannot find their details, having bought two of
their devices at the NEC show back in February and now needing to get in
touch as one of the knobs has broken.

The senility is so bad I can't even remember their name :-(

TIA

Len
