Attaching an Atkins & Porter Ogee clock I picked up for $25. It does have the hands,original weights, and pendulum. Missing the bottom pane. Top glass is old(wavy). Any idea on what the bottom pane might have looked like? Reverse painting or mirror? There are no markings on movement. Did they mark it at all. Case seems like it is in great shape. One nick and no cracks on venner at all. Obvioulsy not cleaned up yer. Did some research and seems like these ogee's from Atkins get decent prices. Not asking for price, but why they are higher than most. Any idea on years of productions? Any advice or opinions appreciated, thanks.
