That gun looks like it hasn't done much work
- it looks to be still "on the face"
- it also looks to have been oiled and stored for a long period of time.

The engraving looks "uncarried" and if the bores are good
then it was probably cleaned well before being put away.

IMHO, US$3300 for a gun like that is good value if in the conditon
is as described.

For those who are looking for a bargain, that;s a cheap way to get into
an English double.
