Offered is a pristine Christian Becker Analytical Balance Scale. This is a Chainomatic model, with all the bells and whistles of the day. It has magnetic dampering and is equipped with Auto-Dex, a moveable index plate that eliminates delicate adjustments and saves time when weighing extremely small quanities. These were major inovations back in 1915, which is the about the time this scale was manufactured. This balance is totally intact, it even has the original "dumb-bell" rider weight that is positioned along the top of the notched beam. The gold chain is the heart of the Chainomatic system. Equilibrium is achieved by turning the exterior rotary dial, elevating or lowering the carriage ( vernier ) on the graduated column. This scale comes with a third pan, for use when conventional balancing is prefered. Research has revealed that the Becker Company used African mahogany ( from Ghana, formally the Gold Coast ) for their cases, which was aged for five years before being sent to the cabinet shop. The aged wooden case has it's original "French" style hand polished finish. The brass components have retained their lacquered protective coating, and show no signs of oxidation. The source of agates for the bearing points and knife edges were from select stock found in either Russia or South America. If it weren't for some very minor blemishes due to age and use, this piece would be in showroom condition. The front access door is counter-weighted, the rear door is not. All the glass is original. Dimensions are 17"W X 19"H X 9"D. The flawless black glass base makes this scale quite heavy, it will probably weigh around 28 lbs. when all packed up. I do my own special packing, and charge absolutely nothing for packing and handling. I will invoice the winner once I get their zip code, an accurate shipping cost can not be calculated until then. I go the extra mile to get my buyer the very best shipping rate possible. Disregard eBay shipping calculators, they are not accurate. This scale will ship within the U.S. for around $70.00 ( via UPS Ground ). Insurance is optional. I offer a total refund if the scale is not all that I've stated. Please take a moment to review my feedback. I sell high quality items and provide top satisfaction. Shipping is done the same day PayPal clears. Thanks for looking over my auction.
