Drag Weight Reel

Drag Weight Reel
Fly rod question- reel action?

I have inherited a fly rod which sat unused in an attic for a number of years . The reel just “free spins” and there doesn’t appear to be any drag action at all- Is it broken, or do I just need to adjust it somehow? I’d really like to use this takle to fish with, but just don’t know if it is usable. Any help is greatly appreciated!
This reel has no markings, but is attached to a 8′ or 8.5′ 7 weight rod-

Depending on the age of the reel, some have little or no drag, thus you have to palm the reel for drag:a technique where you press the palm of your hand against the spinning creating more drag on the spool as the fish takes line.
