Daniel Slote & Co. Catalogue, 1887. Has quality images of the Palmer Duplex, the A. T. Cross Stylo, and the Livermore Stylo. Includes exploded views of the A. T. Cross and Livermore pens, as well as replacement parts lists.
Robert H. Ingersoll Catalogue, 1898?. At page 50, there are images of several pens including an “Ingersoll Pen”. There are also additional ads for this pen at pages 64 and 84. I have several of the Ingersoll pens manufactured by the brother, but this is the first time I ran across an Ingersoll pen from the 1890’s. I have no idea who made the pen shown in this catalogue. Any thoughts are comments?
This is a page from “The Outlook” from 1894 showing an advertisement for an Ingersoll fountain pen. There are three other pages in this volume reflecting the same advertisement. This does not appear to be the same pen as the one shown in the Ingersoll catalogue shown above. However, it is also sold by Robert H. Ingersoll.
