I have been hunting for a good site for Pam straps for a while, there are some excellent companies out there selling some magnificent examples but i did not want to spend as much on a strap as i did on my watch. US sites, for the UK market seem very expensive and European sites are limited.
I stumbled across this site and thought for UK Pam fans it might be useful. I will be ordering a matt black one with olive drab thread stitching and box stitched on Monday for my 'ghost' so will let you know what it is like when it arrives.
