The Montblanc 215 dates from 1957 to 1959 and was produced in black, green, grey and red; the black examples in particular appear comparatively often on collector platforms like eBay or with specialised dealers (e.g. penboard.de), so that with patience working pieces can be found. Suitable pencils are the models 275 and 276; the matching piston fountain pens are the models 252, 254 and 256, which differ mainly in size and diameter (the higher the model number, the larger the writing instrument). Concrete value statements are difficult, since the price depends decisively on the state of preservation; flat-rate market values do not exist.
