Pre-27 nickel 3 1/2 inch barrel accessories value

[mojave30cal]

I'm searching for accessories values for the S&W pre-model
27 from the experts. In particular, I would like to know what
the values are for the gold box marked for the nickel 3 1/2
inch pre-27 in poor, good and excellent condition. I know
these are scarce to rare. In addition, I would like to find out
what the value is of the cleaning tools; brush, rod, mop, and
the sight adjustment screwdriver. Also, what are the docs
valued at?

This information will be used to help negotiate a fair price
for a 1950 pre-27 with 3.5 inch bbl. in nickel that is grossly
overpriced, and missing all these accessories, including the
factory letter, which I know costs $100.00 currently. Hey,
it's worth a shot.

Any help would be greatly appreciated.
