Condition new condition -- fully functional --
no scratches, dents or rust -- all original parts -- 100%
original finish -- in a word... Perfect.
Condition appears new -- fully functional -- all
original parts -- minor scratches -- no dents or rust --
90% original finish or more.
Good Condition minor play wear -- fully
functional -- some scratches -- no dents -- may have
surface rust, but no pitting -- finish must be 80%
original or more -- original parts, with the possible
exception of bolts and screws, (the replacements must be similar to the
original bolts and screws).
Condition fully functional -- may have replaced parts
-- surface rust and minor pitting -- some scratches -- minor dents, but
gun displays well -- finish must be 50% original or more
-- acceptable to most collectors.
Condition scratches and dents -- rust and pitting, but
no holes -- minor parts missing -- finish is less than 50%
original -- gun may not operate, but appears as
though it would -- does not display well.
rust, pitting and holes -- missing parts -- does not
operate -- does not display well -- can only be used for
conditions are subjective. For example, a gun may
have less than 80% bluing, but still be labeled "Very
Good" if it is rare and I consider it to be in "Very
Good" condition relative to other guns of the same model
that I have seen in my years as an airgun collector.
