[Konvas] Film thickness? (off-topic)

Hey all,
This is off-topic, but how do you find out the thickness of a particular
film? I bought an Operators Manual for a FASTAX 16mm camera that came
with a (supposedly) working WF3 Fastax (all I had to do was pay for the
extra $20 for the camera shipping).
It says inside the door:
CAUTION
to avoid damaging camera
USE only fresh
full pitch (.3000")'
WOLLENSAK FASTAX FILM
DO NOT let door
when removed from camera
rest on viewing prism
Looking in the Operators Manual (which has a lot of information, btw,
and not just related to the WF3 model), all the models that they made at
the time are listed. It says the following for the WF3:
Catalog No.: WF3
Frame size : 16mm FF (full frame)
Film capacity: 100'
Min. Speed PPS: 150
Max. Speed PPS: 8000
Camera Type: Framing
Lens Mount: FX1
Std Lens: 2" f/2.0
Te*: 1 / 3 x PPS
(someone has written above it: 1 / 3 x 4000 = 1 / 12,000 sec)
Size and Weight: 12" x 12" x 12" 25lbs.
Shipping Size and Weight: 17" x 16" x 16" 50lbs.
Voltage Requirements:
WF01 Goose AC Volts: 30 Min / 280 Max
WF300A DC Volts: 11 Min / 28 Max
The mathematical formula Te* (actually, the "e" is extremely small, but
I am typing in ASCII) looks to mean the effective shutter speeds. I
believe PPS means "Pictures Per Second". Btw, there are a good many
other cameras, with their information, listed.
On another page, it lists the camera as a "Category I" and shows the AC
and DC speed curves. DC is listed from 8 Volts (2.3 Amps) to 28 Volts
(3.0 Amps). It shows a graph with "Applied Voltage", which is higher,
and "Operating Voltage", which is lower - so an 11V applied voltage is
an 8V operating voltage.
Actually, for as boring as it may look, it is absolutely fascinating
stuff. The schematics, curves, and everything else are in there, so if
the camera does work (and I can find film with a thickness of .2992 to
.3000), then I can start doing really cool things like film hummingbirds
and bees, work with miniatures, and other cool stuff...
But, if it doesn't work, I can always use it as a really heavy
paperweight for when another hurricane blows through...
Whoops, I just realized I was digressing big-time. Back to my question:
how do you find out the thickness of film?
Thanks!
