Signal Corps Technical Infomation Letter

Signal Corps Bulletin

Starting 1 - April 1920, A bimonthly bulletin was published. however it is apparent from the index in the back of the 1932 edition that issues were delayed or missed. making extrapolation problamatic.

Issue #1, April 1920

Issue #2, June 1920

Issue #8, June 1921

Issue #20, June 1923

Issue #24, February 1924

Issue #64, January 1932 (note how the format is that of the manuals made for the special binder)

The Bulletin seems to overlap the letter, up to 1940.

Signal Corps Information Letter

Evidently prior to Dec. 1, 1941 these were published quarterly, (No. 22 being published July 15- 1939) this is what that math would look like-

• 1, 2, 3, =1934
• 4 ,5 ,6, 7 =1935
• 8, 9, 10, 11, =1936
• 12, 13, 14, 15, =1937
• 16, 17, 18, 19, =1938
• 20, 21, 22, 23, =1939
• 24, 25, 26, 27, =1940
• 28, 29, 30, 31, =1941

(the New York Library may have this first edition)
