It sounds like you’re describing a vintage fly fishing rod rack made by Genuine Cornwall Products from Maine, possibly in a rare green finish. Here’s what I can gather based on your description:

Key Details:
1. Maker: Genuine Cornwall Products
– This was a well-known manufacturer of fishing tackle, particularly in the mid-20th century, based in Cornwall, New York (not Maine).
– They produced high-quality rod racks, fly boxes, and other fishing accessories.

2. “Maine” Connection:
– If the label says “Maine,” it might indicate a special edition, retailer branding, or later production.
– Alternatively, it could be a misattribution—Cornwall Products was primarily based in New York.

3. “Rare Green” Finish:
– Many vintage rod racks were made of wood (mahogany, walnut) or metal, but a green painted or enameled finish would be unusual and collectible.
– Could be a custom or limited-run color.

Collectibility & Value:
– Condition matters: Check for original paint, labels, and structural integrity.
– Rarity: If truly a green version, it could be more desirable among collectors.
– Estimated Value:
– Standard vintage Cornwall rod racks sell for $50–$200+ depending on condition.
– A rare color or unique variant could fetch more.
