Well, as has been pointed out, there are a few questions to ask yourself: can I afford it? Do I really want it? How many have I ever seen just like this, and in this condition? ...... I just happened to walk into a local gun show a few years (2 or 3) ago, and a guy had just put a 3 1/2" 27-2 in the wooden presentation case, with papers and tools on his table with an asking price of $650. I suppose that I should have spent time inspecting it, and trying to bargain with him, etc., but I had my wallet out before anyone else had a chance to even ask to see it!!! I still have it, and although it may not be as pristine as yours, it is in pretty impressive condition. And I shoot it and it is a good gun to shoot, and like my Highway Patrolmen, the weight of the big N frame makes shooting even full magnums pretty enjoyable.
Here is what it looked like back then (papers are under the lid lining):
By the way, is the box numbered to the gun? The 27-2s were made during a time when the presentation case would be appropriate for some numbers, and was phased out for others, which then came in a box. I'm sure no expert on this stuff, but you might want to do a little research, since it is a rather high dollar aquision. This gun shipped in August 1979.
Of course I know that that was an incredible buy, even a few years ago, but the point is that I have never regretted the buy.
Today, I have a set of ivory magnas and a Tyler T grip mounted, as I prefer the feel of this combination, of course I still have the original target stocks, in case I would ever want to sell. Which is very unlikely...this is one of my most treasured handguns.
