For a clear guide on Adlake markings and dates, see Adlake Railroad Lanterns: Dating Markings and Collector Values by Tanner Brumley. The book has photos of common stamps and a handy timeline that helps pin down when a lantern was made.
I've used Brumley’s tables when a seller claimed 'early 1900s' and I needed proof. The stamping style and patent marks usually tell the story. If you're buying online, ask for close photos of the base and any stamps.

Adlake Basics and Historical Notes
The Adams & Westlake Company (Adlake) rose to prominence producing rugged signaling lanterns and accessories for railroads. Their manufacturing timeline runs parallel to big shifts in rail operations: more standardized fittings after 1900, wartime material substitutions, and post-war cosmetic finishes aimed at station and yard use. Those shifts show up in stamping styles, materials, and globe colors — all useful dating clues.
Common Collectible Examples (with Price Ranges)
- Adlake No. 2 (standard black finish, original globe) — $80–$250.
- Adlake 'Louisville' style (distinct crown, earlier run) — $200–$650 depending on stamp clarity.
- Adlake road-stamped lantern (specific railroad name) — $300–$1,000 for rare road-stamped examples.
- Adlake brass or nickel-plated decorative lanterns — $250–$1,200 for well-preserved pieces.
Auction Notes and Case Studies
Case study: A midwestern auction in 2022 listed an Adlake No. 2 with a scarce green globe and original mounting bracket. It sold for $540 after spirited bidding from two collectors who wanted the intact original glass. The lot description included clear base photos showing a crisp 'ADLAKE' stamp, which helped bidders trust the piece's authenticity.
In another case, an online listing offered an 'Adlake No. 2' but close photos revealed a replaced chimney and modern paint. It sold for $95 to a buyer who intended to use it for display, not for a serious restoration or resale.
Authentication Checklist
- Locate the 'ADLAKE' stamp or Adams & Westlake markings—base rim, crown, or chimney are common spots.
- Inspect the globe for maker embossing and fit—original globes often seat snugly and show wear consistent with the rest of the lantern.
- Check paint edges and interior for mask lines that indicate repainting.
- Look for wartime part substitutions or patched rivets; these tell a manufacturing or repair history.
- Compare fasteners and hinge designs to reference photos in Brumby’s book.
Market Sourcing Tips
Search estate sales and small-town auctions first — you’ll often find honest, unadvertised pieces. Use eBay saved searches and set alerts for 'Adlake lantern original globe' or 'Adlake road stamped'. When buying sight-unseen, request close-ups of the base and globe and ask about shipping packaging. Expect to pay more for glass that's intact; many sellers discount heavily for cracked or replaced globes.
Conservation and Repair Advice
Conserve original finishes. Clean with mild detergent and a soft brush. For light surface rust, use a rust eraser or fine steel wool under low pressure, then apply microcrystalline wax. Avoid repainting unless you can match the original factory color exactly — collectors prefer honest wear. If you replace a globe, note it in any listing and keep the new and old parts together so future owners can see what changed.
Parts and Rarity
Some globes, especially colored or embossed advertising globes, are much rarer and can double or triple a lantern's value. Road-stamped examples for smaller or defunct rail lines often command premiums. If you source parts, try to verify that replacement components are period-correct and from the same maker when possible.
Start Collecting
Adlake lanterns reward a patient approach. Start with a common piece and compare it to Brumley’s photos to learn stamps and construction.
