In the same period of the [[Omas 361|361]] ogival shaped were adopted for other models and led to the [[Lucens|Lucens Ogiva]] and new ogival versions of the old [[Omas Extra|Extra]] model (called [[Omas 55x|555/S]], [[Omas 55x|556/S]] and [[Omas 55x|557/S]]), These were celluloid made with a red or yellow transparent window, and there were also variants with metal cap. The faceted forms were also kept, for both the [[Omas 361|361]] and the new '' Extra'' series with models denominated [[Omas 55x|555/F]], [[Omas 55x|556/F]] and [[Omas 55x|557/F]]. | In the same period of the [[Omas 361|361]] ogival shaped were adopted for other models and led to the [[Lucens|Lucens Ogiva]] and new ogival versions of the old [[Omas Extra|Extra]] model (called [[Omas 55x|555/S]], [[Omas 55x|556/S]] and [[Omas 55x|557/S]]), These were celluloid made with a red or yellow transparent window, and there were also variants with metal cap.
