I've got the model with no check and no handles - you have to use the rim and your figer in one of the holes. It stops you from putting too much pressure on a fish, and on the small rivers I fish, nothing can run that far.
I bought it at an antiques auction about 20 years ago for £30. At that time Cliff Adcock was charging £70 for that basic model - checks and handles extra.
I don't think he was charging much more than a hundred or so when he gave up. The new owner, Ray Hyland, has attempted to make the business profitable so they're a bit more expensive now
Centre pin or float reels for Steelhead, Barbel, Roach and others.
