The proceeds were to help the development of aviation In total about 12 different ones were issued in 1913 These are difficult to find and most are expensive They have quite a history... the last one prepared in Aug 31 1913 was never used as the pilot was killed in a test flight. |

I'm going through the 1923 to 1933/37 airmail stamps. Is there any way of diferentiate used stamps that used to have grilled gum, other than to have them on cover or with full pm? Thank you very much.

According to Michel stamps with grilled gum were printed on surface-coated (chalked) paper,while the others were printed on ordinary paper.If you can spot that difference,you should know what are what. The 1932 series was printed on coated paper only.So they can be used as reference.
