Ilco lock, Schlage C key way, Pinned 7. Key hand cut 7 from a SC4 blank. Bow cut back with a Dremmel, side milling extended. Then used space and depth keys + a Lishi tool to cut the bittings. Bible was drilled and tapped for set screws. Custom key pins and drivers were turned on the Dremmel with needle files. I never thought to make it a Travel Bug till explaining caching to a customer. Tracking number stamped on the lock and a tag on the key.
