it is rare because it is a configuration or combination of features that does not make sense. You have old school classic mannlicher stock with a modem stainless finish. Very few were made because very few wanted that. I remember giving this a hard pass when new. In any caliber, no thanks.
It has the same appeal to collectors as any other low number item. Some of the most valuable collector guns are failed or defective recalled or sold in limited numbers because they were impractical or in this case BAD taste.
