Start by identifying whether it is an intact extinguisher, empty decorative tank, converted lamp, cocktail shaker, or modern novelty object.
Auction records are market evidence, not a final appraisal. Condition, authenticity, provenance, completeness, size, rarity, and demand can materially change value.
Quick value checklist
- Photograph the full item, maker plate, serial number, model, labels, case, accessories, mechanism, and damage.
- Measure size and note weight, pickup limits, working condition, missing parts, and safety concerns.
- Include receipts, manuals, keys, attachments, prior repairs, provenance, and restoration records.
Key value drivers
- Copper, brass, maker, label, condition, completeness, and decorative demand drive value.
- Converted lamps compare differently from intact safety equipment.
- Pressure, residue, corrosion, missing labels, and safety risks need caution.
