O.D. Jennings coin-operated machines

Evidence to collect

Photograph the complete front, rear, side and base; every casting mark; mechanism plates; coin entry; reels or wheel; payout and jackpot assemblies; award card; locks; cabinet interior; and any restoration receipts or old photographs.

Identification and originality checks

• Record every casting and mechanism mark.
• Check jackpot and payout assemblies for completeness.
• Repainted cabinets and reproduction reel strips should be disclosed.

How to compare value

Compare the exact model, denomination, mechanism completeness, originality, cabinet condition, restoration quality and legal transferability. A visually attractive repaint and a documented original finish are different collector propositions.

Primary and museum sources

• Use period catalogs, patents, machine labels and established collector references for model-level attribution.
