Knabe sunken block

[Dennis Benson]

List,
I have a customer with a Knabe grand from early 1900's (6'2" I believe).
It was restored in 1983 and a falconwood pinblock installed.
Now the block has dropped to bind the action stack. It's wedged in pretty
tight. The block is apparently screwed in from the bottom.

        Question? How do I get it out and is it repairable?
        Any suggestions would be greatly appreciated.

        Thanks,  Dennis Benson RPT
