wurlitzer action brackets

[Fred Brown III]

I worked on Wurlitzer grand yesterday that the hammer line had fallen to
the point of losing about a 3rd of the key travel. When I pulled the
stack off to do a course adjust of the capstans(2 1/2 turns each) one of
the brackets fell to pieces on the keys. Both it and the other interior
bracket seem to have been epoxied together by a preceding tech. I need
to find replacements for these(no I'm not going to try and do a better
job of gluing). Does anyone know who would have made this piano probably
in the late 80's to early 90's. My guess is Samick but I thought that I
would check with you guys before proceeding.
thanks for any help in advance
