This Taylor 6450 7-day barograph is shown in the 1964 Taylor catalog, available on this website. It was still shown in the 1972 catalog. This appears to be a later version in that it has 5 aneroid cells instead of the usual 3. The chart drum runs on 120 volt AC. Mine works well, motor problems are the most common mode of failure, perhaps because it was designed for 110 VAC instead of the 120 VAC now standard in the US?

I have adapted mine to operate using a 31 day monthly chart, using a Nearpow power controller that increments the power to the barograph to advance at a slower rate. Monthly charts are available on eBay from seller bradslocum. JPEG images of the original 7 day charts can be found on the Taylor catalog webpage of this website.
