This is a 1918 (or so) gun, so the gold medallion grips would be right.
Presumably they are numbered to it, probably in pencil on the inside of the
right grip panel.
As a 99% gun, with the original grips in equal condition, the gun has
collector interest. Its collectible, but I say that grudgingly, or with a
bit of hesitation. Its a good example of a K-frame from 1918, and its in
the scarcer 32 Winchester caliber. Other than that, it doesn't have a whole
lot going for it. Its not a target, which would command a huge premium in
that condition.
Its hard to know what the guns true worth is, to the penny. All things
considered, I think its value is more in the $700 range. One of the problems
you run into is that most 32/20 owners like to shoot them, and this one is not
a shooter. So a large part of the interested collector community is not going to
be interested ! And that tends to hold the price back. If it were a target,
you'd be looking at $1500 to $2000 for that condition.

to get an idea of what they sell them for, if they have any.
I think at $1000, you would be a long time getting your money back.
