Struggling to search your website. I believe you might be able to supply a replacement thermometer for a large Boyce Motometer. I don’t think this one is an original. The thermometer case looks like it should unscrew from the housing but it is so tight I can’t budge it. If you can supply a replacement I will unscrew it though. One of the 4-40 screws is missing too.
Thank you,
Hugh
