I thought/think Nikola's gun is more in line with this 1915 offering from Simpsons LTD...with its asking price of $ 1,995.00 USD.

Nikola's gun has thin bluing along its barrel and there appears to be a dent on the "island" of the trigger side plate. It also has a dent/chunk along its back, on the back side of the frame "ear" as seen from the right-side photo...and a small chip of the left wooden grip under the thumb safety...(Yes...call me nit-picky...).
Assume pricing at Simpsons is 20% high for their retail trade...I see that gun at $ 1500-1600...
BTW...I do not doubt someone will pay $ 3K for that 1918 that is offered at the Simpson shop...
