1967 was Canada,s Centenial year.As part of the celebrations a Worlds Fair was held in Montreal.The Russian arsenal at Tula made up a series of Exhibition guns for display in the Russian pavilion.The Gun illustrated is typical of the more elaborate guns seen in the Russian exhibit. I am aware that following the exhibition, the guns were sold.I would not be surprised if the gun is found to be one of the guns from this exhibition.
In past years other less elaborate guns from this exhibition have been seen at Canadian gun shows.
