That is exactly like mine! How did your brother acquire his? The story I was told that it was used by the Russian Olympic shooters and they would sell them after to take the cash back to Russia. Highly doubt it is true but it is an interesting story. Do you have any info on it? I've searched everywhere and cannot find anything. Mine has the original case, cleaning equipment, large wooden palm rest and a butt hook. All numbers match. Any idea what they are worth?
