Just out of interested and deviating away from the tread of this link, I found the following link on the “trails” brackets for the L42A1. This link also has an, interesting view of the No.32 telescopes found on the No.4 (T).
Never knew they fitted the Art II scope on the L42. But then I fitted the Kalinka PSOP to the FAL. inch or metric. using the Williams QD pro mount. Performs well in semi auto. . Gary
