I have a Mono GS1 Strap - Short, 40 - 46", 101cm - 117cm - Jet Black Sharkskin for sale. Condition as new.
Bought on a whim, used twice now surplus to my needs (once in my profile pic). Yes they are a great strap but I can live with my old Warwick strap.
I can photo this but it would look the same a any picture you can Google - however if you want a pic, PM me and I will do one.
