Chelsea Shipstrike Brass Clock And Barometer- With Stand - Read Description. I’m not sure how old this is, but I would think it’s more modern than antique. This needs some refurbishing to be perfect. The clock does work, but the glass won’t stay on the cover. I’m not sure how accurate the barometer is - it is missing the key to calibrate it. The glass on that is also cracked/broken. There is some tarnish on the backs. Please see all photos.
