Hello from Virginia,  Any chance that someone on the group has a few
of the composition "screw-in" valve covers for the early Kimball stack
of 1914 or so?

This is the cover that screws into the top of the stack and has a pin to
guide the valve.  By screwing this cover up or down, you can adjust the
valve travel.  If you have six or so spares or so, please contact me at:

Thanks for looking!
