As-grown and proton-irradiation damaged crystals of the quasi-one dimensional organic conductor (fluoranthene)2PF6 are studied by static magnetic field gradient spin echo electron spin resonance. The parallel-to-stack diffusion constant 
varies sample dependent by a factor of 50, just like the ratio 
. The restriction of free diffusive motion of the conduction electron spins of as-grown and microstructured crystals is analyzed.
