Hi, it is official, my second 111 is on its way. What kind of 111? ?????? The 111B which was in transition because it is only stamped 111B and has an Optimus sticker. Also the cookie control knob is an early feature, as is the slot type of SRV. I know that it is original for sure so the inscription on the burner should tell me if it is pre 62 or 1962 to 1969. However early feature show before 1965 if I am right. Will see !! Please, if you know more, let me know. Thank Will add more when I will received it in 3, 4 days.
