The 361 introduction led to a number of new features both in the stylistic and technical aspects, because for its production were adopted the new ogival lines, with a single decorative ring on the cap and the piston filler was used as filling system for all the OMAS production excepted the Extra Lucens who stayed with the stantuffo tuffante, arrow clip and three rings on the cap, remaining in production for all the '50s, produced without the two-tone nib, and only in medium and large sizes and all black color.
