Restored = bringing back a marginally or unserviceable gun to "as original".
Refinished = all original mechanicals and wood "refinished" to "fresh" but not necessarily "as original" condition; e.g. an oil finsh on a stock take was originally lacquer.
Freshened = all original mechanicals, thorough cleaning and addressing of issues; e.g. putting a gun back on face, cleaning/oiling the stock.
I know this leaves a lot to interpretation and others may not agree. Perhaps a standard definition of each term should be developed similar to the NRA condition standard. Still subjective but maybe it at least would help with the major items such as rebluing, restocking, etc.
