Pathéscope

Background
When the 9.5mm film format was introduced in the United Kingdom, Pathéx was rebranded as Pathéscope.

(Mid 1921?-1925?)
Logo: On a black background, we see a white triangle with a film reel overlaps the triangle, with the 3 words "SAFETY FILM" on the left, right and top, albeit is in the outlined top. We fades in to see the words:

PATHESCOPE Presents

in a script font, which then overlaps the emblem.

Closing Variant: On the closing variant, the text "A PATHESCOPE FILM" is appeared on the emblem.

Technique: A fading effect.

Music/Sounds: Silent, or the opening theme.

Availability: Rare. Seen on many Pathescope films in the UK, such as The Alarum Clock and The ABC of Aviation, which can be seen on YouTube.
