It is difficult to tell the condition of the gun without more detailed pictures. But, with that said, I think the value may be more that those quoted above especially if the "dull" finish can be improved. The presentation case is probably worth $450-500 by itself. The "coke" grips will bring about the same as the case too. The original tools (although missing the brush) are valuable too.

If the gun is refinished, then all bets are off. JMHO.
