Bedroll/Swag straps made by Al Ainsworth at Howling Dingo leather. Very well made using traditional leather working techniques,incorporating solid brass fixtures and even has the edges of the leather rounded off. Al can be found on FB and also has a shop on Etsy.

Note the oversized straps for loading the bedroll with equipment
