In my teen years, I shopped at Army surplus stores in search of fatigues. Who would have thought of military surplus as a furniture source? Thanks to a reader tip, we found this Old Military Field Desk for $199 (used) or $299 (unused) at Coleman's Military Surplus. I might keep the work surface folded down and use the piece as an office storage chest.
