This vintage weather station was produced by Springfield Instruments - a fine line with a reputation for high quality weather related instruments. This item is in very good pre-owned working condition and does NOT come with a key for calibration. The wooden plaque is in great condition and  all gauge are in working order (there is possibly some minor signs of wear, which is normal for any vintage piece). Dimensions are 16 inches, by 7 inches, by 2½ inches (Please Note: all dimensions are approximate and rounded off).Does NOT have key the weather station is in great condition works perfectly I also have the couple other Springfield weather station barometers along with many other items in my store so please check it out.
