I have the same filmstrip (1930 Mechanical Features) and after looking at the frame on my film strip that shows both the 1929 and the 1930 air cleaners side by side, the decal depicted in my filmstrip is not identical to the decal shown in the photo above.
The lines of the printing below the words "Air Cleaner" on the frame in my filmstrip are tapered not even. That is to say the first line of print is longer than the second line. The second line of print is longer than the third line and the third line of print is longer than the fourth line.
Other than that the decal depicted in the photo above looks great!
