The dating system
NPT = Nickel plated trim NS = Needs sac PF = Plunger fill PR = Plunger RBHR = Red and black hard rubber RCHR = Red chased hard rubber RG = Rolled gold RHR = Red hard rubber RRHR = Red-ripple hard rubber, RT = Ring top SGM = Solid gold mounted SF = Silver filagree SFD = Silver filled SGF = Solid gold filagree SN = Section SPT = Silver plated trim SSM = Solid silver mounted TD = Touchdown filler TR = Tassie ring VM = Vermeille© 1995-2017 Tony Fischier and The Parker Pen Company®/Sanford Ecriture.
ED = Eyedropper filled FU = Filler unit GF = Gold filled GFF = Gold filled filigree GFM = Gold filled mounted GFT = Gold filled trim IF = Ink feed IM = Iridium LF = Lever filler MBL = Marble MHR = Red and black mottled hard rubber MIB = Mint in box NB = Nib NF = Never filled. Untouched, unfilled pens, not currently available in stores.
Hence a "47" marking on a 1930's pen indicate that the pen was produced in the fourth quarter of 1937, not 1947, which is a common misconception.
In the second quarter of 1938 this system was however changed to save production time, and a new date code, using a system of dots, was adopted.
The following codes should be used to establish an overall condition, rather than be taken literally.
It has been assumed that Parker began marking some of their pens on the trim or cap bands to allow for dating in 1970.
Right Oblique has the largest surface on right sided of point. 0.000039 inches) To be stamped 10K the layer must equal at least 1/10 of the total weight of the item.

Possibly anticipating the 1980 official start of date coding in France and the UK, this could have led to the presumption that the dating actually began in 1970, but proof of this has still to be found.
The quarter marker changed in 1988 from E, C, L, I to III, II, I or none (last quarter) according to the below table.
