I used to buy patchboxes. The were often too wide or narrow, too long or short, and looked much like everyone else's patchboxes. The last one, I bought the kit from Jim Chambers. It is much thicker, and if you are careful, you can make a better hinge, and either an identical copy of an old one, or, in your case, one with the exact type of eagle you want. It takes longer, but is well worth it.
