Excellent — these are builder’s photo and spec sheet for the Norfolk & Western Railway’s experimental “Jawn Henry” locomotive (No. 2300).

📜 What You Have
• Photo (first image): Side profile of N&W No. 2300, with “Norfolk and Western” clearly lettered.
• Spec Sheet (second image): Lists details for the Coal-Fired Steam Turbine, Electric Drive Locomotive — the only one of its kind ever built for N&W in 1954.
This locomotive, nicknamed the “Jawn Henry”, was a unique experimental design — massive, innovative, and ultimately unsuccessful. It was retired in 1957, making it a rare and highly collectible subject among railroad historians and fans.

💰 Value Estimate
Because of its uniqueness and short service life, items related to the Jawn Henry are much rarer than typical builder’s photos/spec sheets. Collectors and historians often seek these.
• Individual photo of No. 2300: $50–$100
• Spec sheet alone: $40–$75
• As a matched pair (photo + specs): $125–$200+ depending on condition and buyer interest
Some specialized railroadiana auctions have seen Jawn Henry material go for even higher, especially when original and well-preserved.

📈 Why It’s Valuable
• Only one Jawn Henry was ever built.
• It’s one of the most famous “failed experiments” in U.S. railroad history, making it highly collectible.
• Fewer builder’s photos/spec sheets survive compared to more common locomotives.

👉 This set is worth considerably more than your N&W steam engine photos because of the rarity of the subject.
