Great info, Joel! One question, I was told somewhere that the Brooke's Brothers IR's were of a different leather called "Copper Harness". Have you heard this anywhere or are you pretty confident it is the exact same leather as the Red Wing copper rough and tough?
If it is the same leather, I'm really impressed how you've been able to maintain the lighter color. I've only applied 1 very light coat of mink oil on mine and they look quite a bit darker than yours. I'm going to have to get some saddle soap for my next cleaning/conditioning day. I've already purchased Lexol and some horse oil leather conditioner which I believe is what mustang paste is, but I haven't used either yet.
Thanks again for the info and pics!
