At that price they are playing with themselves, especially as it has double triggers which is something a lot of Mausers in that chambering have. The particular sellers are real wankers and often have guns at moronic prices for sale in some cases for many years.

Here is one at a more reasonable price and with single trigger, however it has also been for sale for months starting originally at $7k.
