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.
