First [[Olo]] models were safeties similar to [[R.A.|R.A.3]] (with clip) and [[R.A.|R.A.0]] (with ring), however, marked with the [[Olo]] logo (an ellipsoid squared with the ''OLO'' inscription inside) both on the nib and on the pen body and on the cap top. These were produced also in laminated gold [[overlay]]s (marked ''18 KR'') always in the two previous measures, respectively called ''Type 3'' and ''Type 0'', and with two filling systems: [[safety]] and [[button filler]], the latter resumed shapes and clip of the [[A.R.A.|A.R.A. 15]], even if the decorations used for the [[overlay]] are different from those of the [[Aurora]] models. | First [[Olo]] models were safeties similar to [[R.A.|R.A.3]] (with clip) and [[R.A.|R.A.0]] (with ring), however, marked with the [[Olo]] logo (an ellipsoid squared with the ''OLO'' inscription inside) both on the nib and on the pen body and on the cap top.
