"Depression" Cancels (1930 Type E)

I have become interested in the USPOD 1930 Type E hand cancels, the so-called "Depression" cancels that were issued for a few months in 1930 but were used for many years in smaller post offices. They are the only "modern" hand cancels that had the state abbreviation at the top with the post office name and no text at the bottom. Also, the 4 bars were straight edged at the left.

Has there been a definitive listing of these cancels published other than the "Catalog of Non-Standard US Postmarks" from 1971?

Sounds like something that would have appeared in "LaPosta", at least a few individual state lists.
