Saved it... thank you, Ron! That certainly bears very close resemblance to the one I saw yesterday. But the patent filing date is 1921. The Kohler & Campbell serial number corresponds to a 1905 mfg. date. The number was on front of the keyframe, so I'm not certain it's the piano's serial number, but it's the only number I could find anywhere. Forgot to mention earlier that it has one of them there well-functioning middle pedals, yup, it raises all them bass dampers at the same time!
