Mitch that is a great looking box. Have you ever tried Minwax Antique Oil or Danish Oil? You can get them from Ace Hardware. I soak green HF's and boxes till they won't take anymore for about 10 minutes then wipe of the excess. Wait 24 hrs and then I give them about 3 more coats after I let each on dry 24 hrs. I haven't had any problems with cracking and doesn't give you the shine like poly but gives it a great natural look.
