OK guys, your patience has been rewarded. May I present the 3/8" socket box!
The hardware was lightly sanded and sprayed with hi-temp silver, with the box itself in hammered green. The lid pivots are stainless steel socket cap screws. They look nice, work well, and approximate the OEM rivets closely. I think I will use these from now on for this type of resto. And the drawer liner matches perfectly.
