A.F. Warren patent ink reservoir Gold Pen nib inserted into a modified nib holder that is fitted to a Bagley patent 3-section pen holder.

The Bagley factory supplied the pen holder, and may have produced the Gold Pen nib holder mechanism on contract, given the extensive capabilities at the factory. This would have reduced time to market and overall production costs for small production quantities.

A.F. Warren  sold an unknown number of the Fountain Pen and Reservoir Dip Pen versions of his invention.
