Great website for tacks - they also supply upholsterer's tack hammers...
http://www.dbgurney.com/home.php?cat=243Established by David Gurney in 1825 - When first founded, the factory sat on Massachusetts’ South Shore in Abington and featured both horse-powered and water-powered equipment, with each tackmaker able to produce 5,000 tacks by hand per day. Forty years later, the company moved to (what is now) Whitman, where it found its permanent home using the latest technology to power the factory – a steam engine. D.B. Gurney’s factory is actually older than the town of Whitman itself; until 1875 Whitman was recognized as South Abington. Initially chosen because of its proximity to the Gurney family houses, the factory allowed the men to easily head home for lunch and is nearly identical to its original state. It is an integral piece of a New England town’s historic center where the steam engine continues to reside even though it has been replaced with electricity.
Probably well worth a visit if you are in the area...
On this line, there is a nail making museum in northern France - all machines still in use and running
