Ian I just measured the straps on two pairs of NOS bags. the longer mail straps are 8" and 8 1/2". The buckle strap including the buckle are both 4 1/2". A used pair measure at 9" and 5" respectively, but these have probably stretched with use and weather. Ron
Thanks Ron...That makes approx. 12 1/2" for both straps...The pattern ones quote 11" for the longer strap but no dimension for the shorter one (annoyingly)...I guess a phone call is required before ordering to clarify that point....Ian
