alligator/crocodile straps

anyone have any suggestions on where to find a strap like the one pictured, with the lighter color in the grain, what i would call an "antiquing" effect

have checked all the aftermarket strap vendors,
and short of buying one from a Glashutte dealer, hoping someone knows where i can find one

btw, this photo was saved a few weeks back from another poster on Equation of Time board, forgot who as i was only saving it to send to a few strap vendors, but just so it's acknowledged up front, i'm probably shamelessly violating someone's personal copyright

any assist appreciated in advance
