Parker '61' fountain pen, the 'Heirloom' model available from September 1956, end of production 1962, length 13.3 cm, largest diameter 12.0 mm, rare "wood rings" on the cap (see pictures). Nib slightly thicker than usual, presumably “B”, colour: black (the colours available were: black, charcoal, rage red, vista blue and surf green), doublé cap. Inlaid gilded arrow in the section just above the built-in nib. The filler was revolutionary for that time: remove the rear (screw) cap, insert the pen upside down in ink and the ink will be sucked upward. It was not needed to wipe the pen after filling it because the exterior of this system was finished with Teflon, small hairline crack in the barrel.
