Selected pages
A look at the ledger.
Every batch drawn at the channery is recorded twice: once in the bound shop ledger (kraft paper, ink, kept dry in the office), once in a plain-text backup. A few pages are shown here so studios considering a first engagement can see what a mill record looks like.

Why keep paper?
A studio that restored a window in 1942 is doing it again now, and the first question they ask is what alloy went in last time. If we want someone in 2105 to find the answer to that about work leaving this bench today, paper is the likeliest medium to still be legible. The digital backup is a convenience, not a primary. The fireproof cabinet is a small filing safe, nothing grand.
