That's not a typographical error, I'm really asking about Reynolds Four-Five-Three. I was looking at a '70s era Raleigh frame that brother Wayne Bingham was building up for his wife when I noticed this unusual Reynolds decal. Was this some sort of special tubing made expressly for Raleigh; was it "ordinary" chrome-moly tubing; or what? The decal looks like one of the simpler 531 insignias - i.e. it says "Reynolds 453 Butted Frame Tubes" - except for the obvious difference in the digits.
