Ringed Sandpiper ID? - Chongqing, China (1 Viewer)

[metroplex]

The couple of curlew sandpipers was photoed on 22th May on the side of Yangtze River, in Chongqing, a city from southwest of China. one of them has a ring on the left tibia. The number on it maybe is AB20398C.

It is not from China, if anyone knows more info about this, that would be very appreciated.

Despite the very good pics, the address is hard to match with any scheme, especially as the lower line is partially obscured by wear (spiling) where the aluminium has peeled up over it. The ring looks typical for one manufactured by Mekaniska (used by many centres in continental Europe). I think the serial is entirely numeric, perhaps 6203980 (or 8203980) with possibly one additional digit at the start or end not showing. Are other ringers able to help?

Thanks Phil, unfortunately, we are unable to get more in from the photos, they only stayed there for just one day.
