Suzkat,
I have been collecting 18th century original and reproduction tools (including some early 19th century tools that are correct for the 18th century) for about 10 years now. My purpose is to make up an 18th century period correct "Field Artificer's Kit" with which I may do what we today call "Military Armorer's" work on flintlocks at reenactments. I have not got a complete set yet, though I have a pretty good selection. All these tools are hand tools and specialty tools used by gunsmiths in the period.
Since you are collecting tools that are correct for your ancestor's gunshop, may I make a couple of recomendations on two GREAT books that will really help you find period correct tools?
The first is Diderot's Encyclopedia. The one you want is Volume I. This is great to see benches, vises and other large shop equipment as well as some small hand tools. You don’t have to spend as much money as Amazon wants in this link, but it shows you what the book looks like.
http://www.amazon.com/Diderot-Pictorial-Encyclopedia-Industry-Archives/dp/0486274284While visiting the gun shop at Colonial Williamsburg in the 1990’s, they showed me what they use to document all sorts of hand tools for their works. Diderot’s Encyclopedia in the Iron Working section is great for the larger equipment, but the VERY best book on 18th century hand tools they suggested is A Catalogue of Tools For Watch And Clock Makers, John Wyke of Liverpool Almost any kind of hand tool a gunsmith or many folks working in the metal trades is listed. I can’t say enough about this book.
