YC Brackets, again

[Farrell]

Perhaps two things here. The growing brackets I just found were on a YC serial number 056801. I've heard that the affected brackets were on pianos with serial numbers starting with "0". Yours appears to be from the same era as mine. I should think the most definitive way is to measure action spread. It should be 112.5 mm. The spread on this action was about 122 mm. Phil Glenn from YC is already in the process of sending me brackets. Thanks all for the info you gave me.
