Well, obviously those are the pawls that drive the mechanism, and if there are spring-holes, there used to be springs (though they may have been deleted as a production cost saving). I notice that the machined cavities for the pawls are both left and right hand, so the wheels should be interchangeable. I haven't yet grasped how the rotation that causes the pawls to extend and retract works, or how the external bolt came into the picture. I also don't yet know how the reel is driven - there must be some gears somewhere. I notice that the reel has not been sharpened all that often - there's plenty of meat left. It's also good to see the interior greased and in good condition. This item should be restorable without too much agony, as long as the gears etc are there and undamaged. Do you have access to a tractor to tow it?
