Alongside counterfeits of current Montblanc products such as Meisterstück, Bohème or Scott Fitzgerald, counterfeits of older writing instruments from the 1930s and 1940s have increasingly been offered in recent years. Typical of these counterfeits are very well-executed imprints that correspond to the original writing instruments to nearly one hundred per cent. The base bodies used are often worthless older writing instruments fitted with the imitated imprints. The differences from the original are usually immediately obvious if one has at least a rough idea of what kind of writing instruments were produced at the time. Original comparisons show typical deviations in shape, material and finish. Anyone wishing to consult historical original writing instruments for comparison can orient themselves to documented collections.
