China: Peking Martyrs Vs New Peking Martyrs

The China Stamp Society Specialized Catalogue says that the 8 cent New Peking Martyr of 1941 is a full millimeter wider than the original 1932 version of that design. But there's no mention of a similar difference of width for any other value.

So, are all the New Peking Martyrs wider than the originals?

Emaxim ----Are you talking about the difference between the Chung Hwa Print and the Da Tung Print..

It is on the 8 cent and the 50 cents stamp and the difference is 1/2 of a mm . 19mm and 19.5 mm .

No, because the original plates were used for all but the 8 cent value which was re-engraved.

Thanks to both. Wish the CSC had been clearer about this.

Here is the information that I have about the two sizes . I underlined it in red ink .

To follow up the original question, if the other New Peking stamp values (non 8 cents) all used the original dies to print the stamps and the colors are the same, what is the best way to distinguish between the Peking Martyr stamps, printed in 1932-1934 and later, and New Peking Martyr stamps, printed in 1941 (excluding the 8 cts stamp)? I recently saw most of the unissued New Peking Martyr stamps without overprints listed in the catalog offered in an auction. How do I confirm authenticity? The CSS catalog for the New Peking Martyr stamps provides information on 2 types of the 10c, 20c, and 50c but no information on distinguishing the 1c, 30c, and 40c or differences of the 2 types of the 10c, 20c and 50c to the original Peking version. The original question and answers didn't clarify this.

You can use the link below to start your search for an exhibit that Kelleher sold in an auction that was entirely about identifying these issues. I had the auction lot last night which includes six PDF's of the entire exhibit but fell asleep and lost it (sorry). It is highly detailed. Best of luck!
