Some Grassi serial numbers
As I promised long ago, I was going to get some information on the Grassi serial numbers. They are from a reliable source.

Unfortunately the information is rather sketchy for both the beginning and the end of the company's production lifespan so I will quote here only the SN upon which there is relative but sufficient certainty.

As it always happens these SN charts are never absolutes so one can always think that if an item was produced at a certain date it might have been sold even several months after.

Apparently Grassi started somewhere in 1960 or thereabouts with a SN of 1000 (unconfirmed SN) so SN from 1000 until 27395 mark the period between 1960 to 1974.


from 27395 to 30266 1974 / 1975

from 30267 to 34880 1976

from 34881 tol 37478 1977

from 37479 to 39871 1978

from 39872 to 41835 1979

from 41836 to 43836 1980

from 43837 to 45619 1981

from 45620 to 47344 1982

during these following years these SN are also an estimation due to a less than regular sales pattern

from 47345 to 53420 1983 / 84 / 85 / 86

from 53421 to 60885 1987 / 88 / 89 / 90

from 60886 to 65645 1990 / 91 / 92 / 93 / 94

mi sono ricordato che c'è anche da noi ..... e fa scopa ......... :ghigno:
