Title IAP Collection Pen #5
Description “Double Saw” Guilloché on sterling silver with mother of pearl inlays by Richard Littlestone
Date Added to Collection July 25, 2014
Maker Richard Littlestone
Materials Cap and barrel: solid sterling silver (925), cap wall thickness .025, barrel wall thickness .040; section: nickel silver alloy C75200; nib: 18 kt gold with rhodium plating for two-tone contrast; clip: 14ga Argentium sterling silver (925). Internal couplers are 360 brass, 6061 aluminum, and extruded acrylic.
Components All custom except for the cartridge converter. The nib is made by Peter Bock, AG and has the Argent Blue logo design stamped into the gold.
Tools / Machinery Used Tool room lathe, surface grinder, Deckel pantograph, various presses, Neuweiler and Engelsberger straight liine machine for engraving on barrels and clip. Logo engraving done with a Nd:VO4 laser.
Process Traditional guilloché (engraving) methods employed using a traditional machine. Precision cut inlays of mother of pearl on the top of the cap and the bottom of the barrel. Deep drawing techniques employed in shaping the barel taper. All threads single-pointed; 4-start cap-to-barrel threads. Cap logos are laser engraved.
Maker's Comments The guilloché is applied to the pen bodies and to the clip using the same kind of hand operated machines employed in the days of Peter Carl Fabergé. The straight line machine, or engine, has no motors, no computers, and no moving cutters. Each cut is performed one at a time, delicately and carefully, to produce a sparkling visual effect on the pen. The engraving is a specially designed non-traditional pattern. The pattern bar used for the body engraving is the same as what was used for the engraving on the clip. 130mm closed, ~85 grams weight. Cap does not post
