Early Pilot Nibs. VI. Size 4

As the nib size increases, the pens become more rare and more expensive. For size 4 nibs I have found two examples: two post-war 53RT units. However, their nibs are significantly different:

Manufacturing date	.Non dated.	.Sep 1954.
Length (mm)	26.7	25.9
Width (mm)	5.3	5.5
Feed diameter (mm)	5.3	5.5
Weight (g)	0.3	0.5
Material	Steel	14 K Au

Basic data of two Pilot nibs of size 4.

Steel nib. Undated. The engraving reads "BESTQUALITY / PILOT / -(4)- / MADE IN / JAPAN".

Size 4 gold nib dated on September of 1954. However, it is not marked with the JIS stamp. The engraving: "MANIFOLD / WARRANTED / "PILOT" / 14 K / -<4>- / MADE IN / JAPAN".

Manifold vs. unlabeled point; gold vs. steel; dated vs. undated… Even their sizes are different despite they were probably not that apart in their manufacturing date.

The undated Pilot 53RT with steel nib.

The 53RT with the manifold nib made of 14 K gold.
