Apparently no one owns an MRN. The band first band pictured was not used in commercial production. The second band is also a picture from Trevor's site, but I can find to evidence to show that this band was commercially used before 1982. Cohiba was introduced to the international market at the Ritz Hotel in Madrid in 1982 in conjunction with the World Cup. At that time Avelino Lara was in charge of production at the El Laguito factory.
Prior to 1982, Cohiba banded cigars were only given as diplomatic gifts. A few others may have escaped the island but they were not available to the general public. Three sizes were made and presented in special engraved chests, the Laguito #1(lancero), corona especiales and panatela. It is generally believed that the lanceros were only personally given by Castro himself.
Sometimes its best to dig a little deeper than the first site that comes up on Google.
