A little bit more info... Here's the copy from a half page ad in Cycling magazine (English) March 15, 1951:
Headline: The best bicycles are BONDERIZED to keep the paint on and prevent rust
Body text: Make sure that the Bicycle you buy bears this process trademark -- which signifies that it has been protected against rust by "Bonderizing," the industrial paint bonding process used by leading manufacturers under license from THE PYRENE COMPANY LTD., METAL FINISHING DIVISION, GREAT WEST ROAD, BRENTFORD, MIDDX.
Visual: English roadster and the Bonderized decal that goes on the underside of the bottom bracket. "BONDERIZED ---Regd--- FOR RUST RESISTANCE"
