Pilot Custom Heritage 92, FM nib, Sailor Jentle Doyou. Pilot Capless Decimo, F nib, Namiki Blue.
I have (ahem) more than one Vanishing Point / Capless Decimo, and the nib assemblies have been swapped around between bodies. This nib assembly is from my first Vanishing Point, but it now inhabits the Decimo body which I find more comfortable to hold.
