Br(E) (0)1019 - 5 images of 3 label variants added. - There are 4 main variants:
#1 catnr 1019 at 6; Warner-Brunswick. Side A without publisher's logo, B with Francis Day & Hunter logo. Addition #1a has a Francis Day & Hunter stamp and I think there is no logo under the stamp, so this is the original label of B.
#2 catnr 01019 at 3. Fox-Trot after title (at 4). Tax code T. Side A still without publ. logo, B with Francis Day logo.
#3 Tax code LT. Fox-Trot below title (at 8). Both sides with Francis Day logo.
#4 Ascherberg publ. logo instead of F.Day logo. However, A has this logo on a type #3 label and B on a type #2 label (see position of Fox-Trot). So type #4 might be the successor of type #2, until Ascherberg was replaced by F.Day?
To complicate things further, an A-side #1 label is added with an Ascherberg stamp; no tax code.
