This group of fountain pen nibs last lived in the Sheaffer Pen Co in Fort Madison, however they are all in envelopes marked Radiant Point Pen Corp, 270 Lafayette Street, New York City. Each envelope is marked by hand with the nib number , brief info and the date 6-12-40. It seems reasonable that Sheaffer was perhaps exploring nib makers for gold plated nibs at this time. Each marked Warranted Iridium Tip. Highly polished Gold Plated finish. None appear to have ever been used – Sheaffer may have tried a few of each and then put them aside for further consideration? Quantities and brief info hand written on each envelope. There are various quantities of nibs in each envelope. A total of 30 nibs in seven different styles as marked on the envelopes. Preserve the history or use them as replacements for your pens that use plated nibs.
