Hi Andrew, you may be already aware of this, but here goes. I believe there were variants of the tone modulator on the A-250, my Model (Serial Number 10248) has the control lever which pushes up and down (obviously an early design). I have seen other later examples of the A-250 that have the improved and much more common tone modulator control that slides from left to right. I wonder how long the earlier vertical control design lasted? On the earlier design, it has a flexible screw attached to the bottom of the control handle so if you raise the handle all the way (maximum volume) you can still push the handle out of the way to the left, so it won't scrap against a lowered lid. You may want to include these two tone control options in your survey.
