Glad you did, because Astra TV, Guaranteed Pictures, and Stuart Productions weren't the only ones to use Winston Sharples' VB scores.
Castle Films had some newsreels on their catalog that features some of his music, too. Here's all the ones I could find:
News Parade of 1939 - last 30 seconds uses final scene from Molly Moo-Cow & the Butterflies
Coney Island - various (from Molly Moo-Cow and Rip Van Winkle, Toonerville Trolley, Grandfather's Clock, and others)
California Picture Book - sword fight in Felix the Cat and the Goose That Laid the Golden Egg
South American Vista - bull staring at red trolley in Toonerville Trolley, horse race might have a Sharples score, but I can't say witch cartoon uses it for certain
Roamin' in Scotland - 2:10 mark sounds very Sharples to me, don't know which cartoon (if any) used it
Mexico - bullfights use music from Felix the Cat and the Goose That Laid the Golden Egg & Toonerville Trolley
I don't know if any other newsreels or other film companies in general use Van Beuren music.
