ORIGIN AND SYNTHESIS OF PLASTICS MATERIALS

9. FINISHING MOLDING PARTS.

Registration MP449 (part 9: FINISHING MOLDING PARTS) Uncertain

Term began: 1946-02-01
Claimant: 2c 4-19-46, synopsis
Class: MP — published motion picture other than a photoplay (numbering series begun 1946)
Finding: registration number MP449 also appears on another catalog entry with a different title; one of the two is misprinted or misread

The catalog entry has a problem (missing date, or a number that does not fit its year), so the renewal check cannot be relied on.
