Re the strap, Geo mentioned in the above pictured article did remake the straps in a fabric with a weave that looked like that, with the end dipped in dope, it could be one of those. I have one, I will dig it out and see if it looks the same.
That's the chap. In some ways I prefer his strap to the faithful AF0210, the buckle and tang are less fiddly to use and I like the doped end, but obviously they aren't as 'authentic' to the original. Both good straps.
