I have always been aware that a rib I retrieved from the factory was indeed flat but remembered some curvature: that was the curved caul. A second slip up in the post comparing Chickering and Steinway rail and style construction of the keybed. I had explained to me at the factory the unglued method used by Steinway but, in the heat of the moment while extolling the virtues of Chickering's system, I contrasted it to Steinways and, erroneously, commented upon Steinways system as glued. The difference in the two lies more in the orientation of the rail and stile within the action cavity. Both are floating. Other differences are characteristic of the keyframes themselves. > they also have the decorative patent date arranged > similarly. I'll check on this tomorrow.

Finally, a third mea culpa: These two B's appear to be dated in the same manner as described above but lack the decorative patent date found nearby on the A's. > > So, to clear up some of the confusion - early pianos had a patent date > stamped just along the edge of the plate, oriented to be read from the tail. > These appear upside down when trying to read the dating and scale marks which > are nearby as they are oriented so as to be read from the front.

Again, the B's lack the patent dating in the analagous position.
