Near mint condition Bosch a little less than 5.5 inch diameter or 138mm across the back fog light lens in the old script of the 50’s.
Very rare version.
This is the same as Bosch 1305601050…051 without the K11125

This has the vertical bend down the middle of the glass.
It has the logo and Bosch script in the middle, Germany and importe de Allemagne under. Difficult to photograph.
