This first-class shop will put in a new selenium cell if needed, along with tuning and replacing the following checkpoints:
Assuming this meter is in fine enough condition to repair, the cost will be around $78 and you will have a superb meter, built to last. I have had a couple done at this shop, and think it a bargain, especially considering the professional excellence of this shop's work.
Or perhaps you can get it into fine shape yourself. I know I could not, but am happy to be a customer of Quality Light Metric. Good luck, either way.
