What is Known about the Columbia Symphony Grand Graphophone?

[Warren]

I recently acquired a Columbia Symphony Grand that has the pull out storage shelves and I an stuck on how to attach the speed control rod there seems to be no way to tighten the small screw that holds the rod in place It's a nice model with a few bruises and all is intact except the moment I put the heavy motor board in place there isn't a way to access the screw that holds the speed control rod in place ANY help would be appreciated a picture would be even better The price was a steal according to everything I have seen

Thanks
