Now, I must say that Speed Astirs were changed in many ways during
their short production run. *Every plane I have inspected was slightly
different than the others. *An example are the fittings for the
headrest. *Some are fabricated, some are cast, some mount to the shelf
behind the seat, some mount to the top of the fuse. *The way control
rods are supported, the actual material the control rods are made of,
the levers...all have had slight variations.

On my plane there was the water dump valve hole and then there was one
other large hole on the bottom of the fuse. *A different Speed had
several small holes to drain air and water in addition to the water
dump valve hole.

Got it! Mine is an early (SN 4005) version and has a few small holes,
which I leave un-covered. Thanks for the information.
