35266 was released as part of an album for children, Columbia J-1. Maybe that still means it was released around the same time as nearby catalog numbers that were individually sold, but maybe not.
Co 35266 - I mean the present website/database, 78 RPM within 45worlds. Within Columbia(USA) the releases are presented by date. I searched for the correct release dates, as the release date mentioned above for 35266 is 3 days after the recording date.
Co 35266 - This website mentions following Columbia release dates:
8 Sep 1939 - Co 35201-10 (start of the red label 35000 series)
15 Sep 1939 - Co 35211-14
22 Sep 1939 - Co 35220
29 Sep 1939 - Co 35228
6 Oct 1939 - Co 35230-32
13 Oct 1939 - Co 35235
20 Oct 1939 - Co 35241-44
26 Oct 1939 - Co 35247-51
2 Nov 1939 - Co 35254
9 Nov 1939 - Co 35261
16 Nov 1939 - Co 35289-90
24 Nov 1939 - Co 35298
30 Nov 1939 - Co 35301-02
Thus weekly releases in (as far as known) numerical order. 35266 is evidently a Nov issue.
This is confirmed by the recording date, 22 Sep 1939, which excludes a 25 Sep release.
Maybe 24 Nov 1939 is an error for 23 Nov?
