[78-L] Last Columbia flag labels

[Han Enderman]

Can someone give info about the label type of 
- Columbia 378-D;
- Columbia 15030-D.

These are (from Ty's ODP):
378D FRANKEL,Harry NOW GEORGE 140359 - - 1/25/25
378D BILLY JONES & ERNEST HARE AS A PORCUPINE PINES FOR ITS PORK 140498 - - 4/6/25

15030D DALHART,Vernon The PICTURE THAT IS TURNED TOWARD THE WALL 140595=3 - - 5/13/25
15030D DALHART,Vernon AFTER THE BALL 140596=2 - - 5/13/25

New issues before these cat.nrs have flag labels; subsequent issues have black labels.
The last flag in the 14000-D race series is 14074-D (Maggie Jones 5-5-25).
Presumably the last flags were released in June 1925, and the first black labels in July 1925.
