Czechoslovakia: What Are Their Scott Numbers?

The following are two (2) postage stamps that I believe are from Czechoslovakia, but I have spent hours looking through the Scott 2009 catalogue looking for them, without any success.



Can anyone inform me of their Scott numbers?

Look like #92 and #93.

I can't help with Scott, but the details according to Stanley Gibbons are:
100 heller red on yellow, Type B (P in Posta with 'extra leg', triangle behind stem above book extends on eithert side of the stem), issued 3.1923, SG 227a.
200 heller blue on yellow, Type B, issued 2.1924, SG 228.
Both are re-engravings of an earlier stamp issued in 1920, designed by Brunner (one of the great early Czech stamp designers).
Both have low catalogue value.

By the color it's #92 and #93 (1923 redrawn issue of 1920) but there is different type for each.

Many thanks to AnthonyUK, David King and timbres667.

Thank you, thank you, thank you!

Now I have found them in the catalogue I cannot understand how I missed them.

Yeah, it's amazing how often that happens . . . particularly maddening in those cases where you KNOW you've seen the stamp in the catalogue but you just cannot find the dratted thing . . .

Those are nice Stamps, Orator. They are supposed to represent "Agriculture and Science".

Here is the 300h from the original 1920 issue. Notice the shading in the leaves that is absent in the redrawn issues of 1923 you have. The 300h vermilion is listed as Scott 78, but the shade variety which appears more like rose is not listed.
