The indicia scan confirms that there is no volume, issue number or frequency present.
Judging from the cover, copyright registration, and the indicia text, it appears this book was originally intended as a stand-alone publication and not part of a series. The Copyright Office treated it as such; the filing is listed in the Pamphlets volume and not the Periodicals one, which is how the Office treats stand-alones. There doesn't appear to have been a copyright filing for the second issue (from 1944), but the cover and indicia point to that being published as a stand-alone as well. This doesn't seem to have become a proper periodical series until the third issue in 1946.
