You haven't given me enough information for me to be able help you. First and foremost is simply the fact that you haven't supplied any photos. I really need photos of the item as well as photos of any marks or writing. Your subject headline reads "Meiselman Imports" but you failed in your description to say whether or not "Meiselman Imports" is actually written on the piece. You also failed to state whether or not the item is marked "Italy", "Made in Italy" or "Italia" or whether or not the country of origin appears on the item at all. Finally, you noted that it is marked "Illodernage". I'm fairly certain that you are not reading it correctly as that word does not appear in English or Italian.
"Meiselman" and "Meiselman Imports" are the same company. How the name appeared on a piece was merely dependent on how the manufacturer decided to assign the importer's name. Officially the corporate name was "Meiselman Imports". The company filed its original request for DOS recognition in New York State on January 4, 1965. It is possible, however, that the firm may have operated at a slightly earlier date before filing for corporate status. On September 2, 1980 the company changed its name to Ben Har Imports. The firm, based in New York City was dissolved on September 21,1981. The company imported porcelain, ceramic and glass household and decorative items from several companies in Europe. Like many import companies they never allowed the manufacturer to reveal itself and rarely, if ever, do we find pieces that include the manufacturer's name or logo. Since the factory or studio is an unknown it tends to restrict prices on the secondary markets.
