Hi Jennifer,
What an interesting vintage camera. Thanks for the nice pictures of it.
Did it come with just the one lens?

I do notice that it will require double sprocket 16mm film.

This format film stock has become less common these days since most
cameras are single sprocket.
It is possible to modify the sprockets in your camera so it can take
the more available single perf stock,
as long as the claw in your camera is a single pull down claw. If the
the camera has a double pull down claw I am not sure how easy it will
be to modify.

I have filed down sprockets on older Bell & Howell double sprocket
cameras to modify for use with single sprocket film. I was able to
do this with cameras from circa 1940s.
Some even older Bell & Howell cameras (ca '30s and '20s) not only
have double sprockets but also a double pull down claw in which case
it is beyond my abilities or willingness to modify.

Look behind the pressure plate as you run the camera to see if there
is a single claw or a double claw pull down. If it is single, you
might consider the possibility of modifying one of the sprocket rows
on the two sprocket wheels.

Another approach would be to track down sources of double sprocket
16mm film stock. Last time I checked, it was not so easy to find
One source is "double 8mm" which is made available. Double 8mm is
16mm double sprocket film with an extra set of sprocket holes in
between each frame, so to speak.
You and your camera would simply learn to ignore the extra sprocket
holes. This could become tricky if you were to rethread the film to
send through the camera again for multiple exposure,
a process which would be better done by winding back while film is
still in the camera.

In the old B&H cameras the sprocket wheels are easily removed so
grinding off the row of "extra" sprockets was a simple matter.
Check to see how the sprocket wheels might be removable. Then it will
be a matter of knowing which is the correct row of sprockets to grind
off, something obvious if you have some single perf stock in hand.
If you are not mechanically inclined you could get a technician to help.

Hope this does not seem like too much info.

It looks like a nice camera with a great lens.

Where are you located?
