These beautiful pens are Parker Striped Duofolds
Parker called the celluloid "Laidtone", not sure what that meant. But goodness, they're pretty! They remind me of modern raden pens. Besides the red/silver and green/brown, there was a blue/silver version and one that was all thin grey stripes, called "shadow wave".
The nibs on mine have seen better days. The green/brown one has got a crack running down from the breather hole and it's pinched on one side. The red/silver one had broken tipping: I replaced it with a spare Sheaffer nib.
They were made the same year: 1941
These two are button fillers: they also came in Vacumatic. Button is not my favorite filling system, but at least it's an easy fix.
One of these days I'll track down a blue one.
