[78-L] Down Beat Western & Gospel Series

[Han Enderman]

The Californian "Down Beat" label (1947?-1949) issued a very small and rare "Western Series"
(as mentioned on the label).
I have a scan of 3002-B Jack Pitts: Ernest Tubbs Talking Blues.
How large was this 3000 series and when was it released?

There was also a possibly even smaller 400 series, pres. intended for gospel
(though the word gospel or spiritual is not on the label).
I have a scan of 401-B by The Sally Martin Singers.
Same question: How large was this 400 series and when was it released?

I assume that both series are from the beginning of the Down Beat label.
All other issues of the label are in the 100 series (100-230), which includes gospel
but no western.
