The Military Museums of Calgary has issued a public appeal to military collectors to be on the lookout for a large number of items stolen from the museum in 2010.

Nearly 600 items were stolen from the museum’s collections, and although some were recovered during a police investigation, most have likely made their way into private collections, the buyers unaware they purchased stolen goods.

Although most of the items could be bought practically for a song, they are really priceless pieces of Canadian history, says Tom Doucette, the museum’s executive director. They include many medals, belts, berets, cap and collar badges, rank pips, daggers and knives, rifles and bayonets and history books.

The museum has posted a description of the missing items on its website.
