Depends on the level of work required and the cost of the barreled action. If you're going to do most of it yourself, sure, why not. If you're sending it out to say, Doug Turnbull, you're looking at . . .what . . . 3k to restore the metal to like new and probably 1500-2000 for new wood. So, think 5k plus the cost of the action.
If you are buying a pre-cut stock and finishing it yourself, you're looking at more like 200.00-500.00 for wood depending on how nice a piece.
The biggest question for an auction gun is this: when they say it is a barreled action, how exactly much does the metal need to be restored? How will you know until you get it? If it is just bluing, hell yeah. But if it's rebuilding the action, the barrel, etc., you're talking major bucks.
What are they worth when done and not all original? Turnbull asks quite a bit for his so . . .
Sure, it is worth it dollars wise if you can sell it or want to, but is it worth it to the average guy? Probably only if you are doing all or most of the work yourself. Bottom line? You could buy a new Winchester brand with case hardening for less.
