Parker 45 Flighters

This photo shows my three Parker 45 'Flighter' pens.
All were made in the 1970s, so all have the 'wide' 'PARKER' logo, and none of them have production date codes stamped on them.

Top → bottom, they are:
a 'MADE IN FRANCE' pen with a steel 'X' nib which is very rigid;
a 'MADE IN ENGLAND' pen with a 14k gold 'M' nib which is slightly 'bouncy' ;
a 'MADE IN ENGLAND' pen with a steel 'M' nib that is very rigid.

The 'M' nibs on these two pens are slightly less-wide than the 'M' nibs on my Parker pens that were made in the 1990s and later.
