help needed refinishing wooden Venetian blind

[mattocks]

The Venetian blind in our bedroom is in good condition despite being 20 yrs old.
The only thing is the finish has faded and fallen off in places.
I would like to refinish it but not sure what to use.
Can anyone recommend something.
I'm hoping something like wipe on poly, which I haven't used, would do the trick.
Pics are of front and back of the blind.

thanks for looking
