It has a similar action as the one you describe. (possibly.<G>) There are adjustment screws within the action, that = can be experimented with, to see what will give you the results you desire. As = these type of actions do not have escapement, per se, there is very fine = balance between blocking on the string(s) and virtually nothing.<G>  = The early pianos were all "experimental", so each has it's own way of = achieving some semblance of "touch". That's the best I can tell you. Of course, proceed = with caution, always.</FONT></DIV> <DIV><FONT face=Arial size=2>FYI, most pianos of this period, had a = very shallow dip, compared to what we see in modern pianos. The Faust Pocket = Companion says "two eighths of an inch", (i.e. 1/4"). The early Chickerings used this dimension.</FONT></DIV> <DIV><FONT face=Arial size=2>To sum up, try for consistancy and = leave it at that.
