The reel came in 4 sizes; 1 - 4. Based on other Cabela's branded reels and a wild guess, I'd say it's a reel for 7 - 8 wt fly lines, maybe?
Some copy from an old catalog page reads:
"Our new CSR (Cast Speed Retrieve) Reels deliver high-quality, dependable performance at an entry-level price. They have a Rulon® disc-drag system that is sealed to keep out dust and debris. And the drag system offers a wide drag range controlled by a large, easy-to-adjust, knurled knob. The cast-aluminum frames and spools are fully machined to reduce the overall weight and to maximize the strength and integrity of the design. Spools sport a large-arbor design that is wide enough to accommodate the backing you'll need in each different model. Oversized, paddle-style handles are easy to grasp and control. Easily converts from right-hand to left-hand retrieve. Available in four sizes to handle everything from a 3-weight line to a 10-weight line. Spools have quick release lever to make for easy line changes."
I have a Cabela's Drake I bought a number of years ago and while it hardly gets a lot of use and I take good care of my gear, it is a nice reel that does everything I ask of it when fishing.
There are also a few CSR reels on eBay so if they have resale value, they must hold up.
