[CAUT] Steinway Broached Hanger History

[G Cousins]

Gang,
I received this reply from John Dewey
Gerry Cousins

BEGIN REPLY:
I do not know the date when Steinway changed from the 
cast holes to the machined (broached??) holes. I did a Steinway “L” 
serial number 428551 which had the large cast holes. I am at my sisters 
and do not have anything to look up the manufacturing date by serial 
number with me. I think this piano was from the “ CBS era “. In 2000 I 
ordered new action brackets from Steinway and they had the machined 
small holes.



I have rebuilt Steinway action frames from as old as 1877 through the end
 of the “CBS era“ and they have all had the cast holes. So far I believe I
 have only rebuilt 1 frame with the machined holes and I do not remember
 what the serial number was.



Sorry I could not be more help. You might try Bill Shull



John Dewey

But I'm pretty sure it was in the early '90's, not late '80's. And this one was likely a decision that, once implemented, went into the action department from one order of brackets to the next, rather that working its way through the various models. Of course, there's quite a time spread from the soldering of rails to when the finished product shows up in for serial numbers, so there is probably a 2-3 year spread in which both versions may occur.
