Ok, This is weird

[Greg Newell]

Del,
         Thank you for your response! I appreciate your experience here. 
You've answered my most pressing question in that it most likely came this 
way from the factory. That's too bad. I will communicate this to both piano 
owners and see if I can get some results from the glide bolt. Thanks again 
for everyone's help!

Greg

P.S. I wonder how many of these I've encountered before and never identified.
