Where can I find info on a rifle that belonged to my husband's father that is a 22 caliber rifle with octagon barrel and is hammerless and pump action with the only word on the rifle being Premier?

I have found very little information on the line of Rifles. Here is what I found. It is a trade name used by various retailers from Italy and Spain. These rifles were imported during the 50's and early 60's to the USA. They mostly made Shotguns.
