From our huge private museum collection: Antique Indian Wars US Cavalry Putnam Horse shoe Nail Cardboard Box. Not sure on the date of this rare items, possibly 1870s to 1890s. Never seen another like it (except for one in a museum). 
From the Internet:

Putnam’s Horse Nails were adopted for general use by the U.S. Army as the “Government Standard Horse Nail.” In 1872, Mr. Putnam’s factory in Neponset used a 200 hundred horsepower Corliss engine to drive his machinery, and it employed over 200 employees in making nails. The company used only machines of Mr. Putnam’s invention, the first of which was put into operation in 1859.

About us: Due to advancing age, we will be selling off our huge private collection. I’ve been collecting Civil War, Early Indian Wars antiques since the late 1960’s and it’s time to let go of things that I love (and find them a new home). The collection is primarily Custer’s Black Hills Expedition of 1874, Civil War, 1870s Indian Wars, Victorian, and Old West antiques. Over the next few months, we’ll be listing hundreds of rare and historical items. Many more great items to come. So, bookmark us and keep watching!

Terms: Items are authentic to the best of our knowledge (or they would not be in our collection) & as described, however, we can’t be an expert on everything, so not infallible. All items are sold “As is” with no returns; but if we did make a mistake, let us know (before leaving feedback) and we will try our best to make things right. After all, we have been selling on eBay for over 25 years with an absolutely perfect record of happy customers!

Shipping: US (lower 48 states) Shipping only. No exceptions!  All items will be shipped insured. If your item(s) (single, or combined) value is $500.00 or more, a signature will be required. No exceptions. We try to combine shipping whenever it’s possible when there’s smaller items of very similar size. But combining items is often not possible, as items packed together in the same box could be damaged. We want your antique to get there safely in one piece! Let us know what items you want combined and we will let you know if we can do it. We estimate shipping (and sometimes a couple bucks handling fee). Shipping is getting expensive, and there’s nothing we can do about it. All items are packed very well and shipped fully insured. Thank you!
