Create a dossier that includes acquisition notes, seller contacts, signed receipts, restoration invoices, and a timeline that leaves no gaps. Add high-resolution images of every surface, inside and out, plus sketches mapping wear, repairs, and maker marks. Cite sources rigorously and label conjecture honestly. Keep both physical and digital copies with indexed filenames. This disciplined packet turns memory into usable evidence, supporting fair valuations, responsible insurance coverage, and informed decisions when conservation choices become complex.
Photograph under raking light to reveal plane chatter, scrape marks, and filled knots. Macro shots capture tool signatures; wide frames establish context. When claims warrant it, consult non-invasive techniques like UV fluorescence to study finishes or microscopic fiber analysis on upholstery. For select pieces, dendrochronology can indicate felling periods. These data points, paired with careful historical research, strengthen or correct attributions. Science does not replace story; it tempers it, making the narrative honest and durable.
