## **1. Understanding the History & Rarity**
The Donald R. Spencer Clear Plastic Cylindar Fly Box was patented in the mid-20th century (Patent #4563834) and quickly became a favorite among fly fishermen. Its design was revolutionary for its time, offering a **compact, waterproof, and highly visible** storage solution for flies.

## **2. Key Features to Look For**
### **A. Clear Cylindrical Design**
Unlike traditional flat fly boxes, the Spencer model features a **cylindrical shape**, allowing for better organization and quick access to flies. The **transparent plastic** makes it easy to identify flies without opening the box—ideal for fast-moving fishing conditions.

A well-preserved vintage Spencer box should have a **tight-sealing screw-top lid** to prevent water ingress. Test the threading to ensure it still closes securely—loose or cracked threads reduce its waterproofing ability.
