This is the second group of color postage meter stamps issued by China.
 

Hi,

thanks for showing these new items.

I was askd by Rick Stambaugh [1], Editor of the International Postage Meter Stamp Online Catalog [2], if you have any further information about it, like model/series etc.

I think it might be a Pitney Bowes connect+ series meter model?

It was temporary addes in the Mainland-China chapter [3] under "HC19"

Maybe you can contact him directly?

Best regards
Thomas

Hi,Thomas

This is a "浙工大 CX51" color postage meter independently developed by China.

Some of the China postage meter in the online catalogue of international postage stamps was also edited by me.
 

This is the first set of meter stamps issued by China.
