I'm not sure but those bags look similar to the stuff that Jimbo makes in Beijing.
He's got a pretty popular website and does some fantastic BMW/URAL/ChanJiang conversions over there.
And he's got a leathermaker too. Good looking stuff.
here's his address:
54' R51/3, 65' R60/2, 68' R60US, 74' Moto Guzzi Eldorado, 95' Mystic
