I bought a 1960s vintage Remington 760 that had been exported to Sweden and returned to the U.S. via Simpson, LTD. The Swedish owner put his elk/moose permit stickers on the stock. Interesting, but not my cup of tea, so I bought a replacement set of wood on eBay.

A man who I hunted with as a kid, hammered a brass bard into the right side of the stock of his Remington 141 in 32 Remington. I thought that it was kind of cool, but my Father explained the decrease in trade/sale value down the road, so I have never adopted this means of keeping track of kills.
