More additions - USA Airmail stamps

I have had two posts on my collection of US airmail stamps so far. Earlier there was no picture of the first stock page of these stamps, there were only pictures of the six stamps from the first stock page there and later I posted the complete set of the twin motored transport plane. Well here's the first stock page now with the few if not all additions to the collection.

Here's a closer detailed look at the new additions.
1926-1927 Airmail Issues #C7-C9, US Map and Mail Planes

10c Dark blue
15c Olive brown
20c Yellow green

1927 Lindbergh's Trans-Atlantic Crossing #C10, Lindbergh Tribute

The world rejoiced when Colonel Charles A. Lindbergh completed the first solo transatlantic crossing aboard the Spirit of St. Louis, the single-engine plane he piloted on a non-stop, 33½ -hour flight from New York to Paris. To mark this historic event, the Post Office Department agreed to issue a special airmail stamp - the first time a living American was honored.

# C11 - 5¢ Beacon on the Rocky Moutains

Increased volume of mail being sent by air enabled the Post Office Department to lower airmail rates in 1928 from 10¢ to 5¢ per ounce. The new 5¢ stamps showed a beacon light atop Sherman Hill in Wyoming, one of the landmarks that made it possible for pilots to find their way cross-country at night. The bi-colored stamp was expensive and time-consuming to produce. After two years, it was replaced by a different and more economical single-colored stamp.

# C12 and #C16 - Winged Globes

Both these stamps are similar in design and actually not very difficult to tell apart. The difference as mentioned in the catalogs is in the no of perforations. C12, the first stamp in the picture above is perf. 11 and C16 is per. 10 1/2 x 11. The perforations can be measured by a perforation guage, but as I dont have one yet, I just stick to counting the perforations using a regular scale and thats how I have identified these two apart. Simply measuring the no of perforation teeth between two cms of a regular scale does the trick. Simpler still, just place both the stamps on top of each other and if the perforations don't match you know you've got both these.
I have noticed one more difference in these two stamps and that is in the shade or density of the violet colour on both the stamps. The violet is lighter and less dense on the C12 as compared to the C16. Atleast this is true with my copies. Need to confirm this with another pair of these. Cool stamps though.

1935-1937 Trans-Pacific Issues #C20-C22

To improve contact with its Pacific Island possessions, the U.S. inaugurated airmail service from San Francisco to the islands of Hawaii, Midway, Wake, Guam and the Philippines. Mail was flown by Pan-American Airways aboard large seaplanes known as China Clippers, named for the 19th century ships that carried tea back to the U.S. from the Orient.Trans-pacific airmail service began November 22, 1935 as commemorated on stamp #C-20, the 25c stamp in the picture above, which bears this date.

# C24 - 30¢ Trans-Atlantic Winged Globe

To celebrate the inauguration of Trans-Atlantic airmail service in 1939 this 30¢ stamp was issued using the familiar "Winged Globe" design from 1930.
