Thanks all. Appreciate the kind comments.
Obtained the strap from a member of another board. As I recall he made the straps from vintage 1960's leather.
The sides are just attached with the one top screw. Others have added a block of wood to the inside of the side pieces and then screwed from the inside compartment. Might do that on this one... maybe.
Tonight I drilled the axle holes for the mid and lower compartment doors. Had a few issues with the middle door but after a little sanding and a minor adjustment on the center metal divider the issue was resolved.
I placed a spacer under the bottom door, just at the bottom, taped in place and drilled the axle hole.
