author
Best known as the co-author of an 1883 handbook on gunsmithing, this little-documented writer is remembered for helping preserve practical trade knowledge in book form. His surviving record is slim, but his work points to a strong interest in the craft, repair, and history of firearms.

by Wm. B. (William B.) Harrison, J. Parish (James Parish) Stelle
Wm. B. Harrison, also listed as William B. Harrison, is credited by Project Gutenberg as the co-author of The gunsmith's manual: A complete handbook for the American gunsmith, being a practical guide to all branches of the trade. The book was originally published in New York by Jesse Haney & Co. in 1883 and was written with J. Parish Stelle.
Because reliable biographical information about Harrison is scarce in the sources available here, not much can be said with confidence about his life beyond that authorship. What does come through clearly is the book's purpose: it was created as a practical manual for American gunsmiths, combining hands-on instruction with historical background on firearms.
That makes Harrison a figure known more through his contribution to a working reference book than through a well-recorded public career. For readers interested in historical technical writing, his name survives as part of a manual that helped document a specialized 19th-century trade.
