Murray 102 - Composer of A is McCrosson (to be corrected in the track info). This record was also issued on Bronze 108 (showing Mc Crosson), and this explains the nr 108 on the Murray label. - Martin is also mentioned on Bronze 107, 110, 111 & 124 labels (as performer or composer). 111 & 118 have a composition by K. Morris. If someone makes an entry for Bronze 108 (and others?) I will add the images. - The Murray 100 series was probably a gospel series. The only image I had until now is Murray 107-B by Pilgrim Travelers, which is also on Down Beat 130 (confirming the interaction between these labels, as DB 102 = Bronze 102, etc.).
Apologies for the incomplete images. These tracks are alleged to have been recorded for Bronze records in 1940. Given that Sallie Martin relocated to California from Chicago in 1948 in order to establish a Martin & Morris office there, 1948 is the earliest they could have been recorded. Given also that Leroy Hurte, owner of Bronze records, stated he was very busy with the label in 1946-1948 but no releases are shown, I would guess those much earlier years attached to the various Bronze recordings are incorrect.
