I saw this pen at a local store. The pen has been serviced and works fine. A flexible stub nib. They are asking $100 for the pen. Can anyone give me any info on this pen from my photo? Is that a fair price? Any ideas when it may have been made? Mabie Todd Patent Jan19 1915. I didn't have a loop with me, and I couldn't read any of the engraving on the nib. Thanks.
