What you have there is a 4x5 camera (lets ignore the specifics of the model for a minute). You may want to read up on 4x5 cameras before trying anything.
Heres a video as well
as this one on using a 4x5. If you are trying to get into film this may be a big (and expensive) place to start. First off this camera will require you to load each slide individually (unless you can get the 120 back as mentioned). Depending on what type of film you are using you are looking at somewhere around 5$-10$ a shot (not a roll, thats a single image cost). On top of that you will need a place that develops 4x5 negatives. This is hit or miss and if you are in a City you will most likely have better luck (here in Philly there is still a place that does it) . If you really want to dive deep you can develop this stuff at home. I would first secure a place to develop before shooting but thats just me.
As for the mechanics of the camera there are a few things to check. As this is a bellows style camera (accordion looking thing) you may have some light leaks depending on how it was stored. Over time the fabric can degrade. This can be fixed in a variety of ways, if you look around the web you will find lots of how too's. you can check this by shining a flashlight in the camera in a dark room. This will yield obvious leaks but when you start shooting you may find smaller leaks as well.
A camera like this has both the aperture and shutter control in the lens. In most of the stuff I have ever restored the faster speeds tend to work but the slower speeds can stick over time or be completely inoperative (typically turning into a bulb mode situation, sticking open). Depending on how bold you are you can fix this your self. Often times its just a result of dry oil and dirt which can be thinned and cleaned with naphtha. This however will require taking stuff apart which you may not want to do right away. Load the shutter at various speeds and just make sure its opening and closing for now. Make sure the aperture blades move when adjusted and if both of those things are working you should be ok to start taking a photo (quality not guaranteed).
You can also get most of the surface dust of with a
hand blower and some Q-Tips. Room temp water should be fine on the Q-Tips or any kind of non alcohol lens cleaner is what I use. You should free the focus rails of any gunk, you can thin the old oil off them with naphtha as well.
As I said earlier this is an interesting place to start film shooting. I by no means want to discourage you from using this camera but I would simply personally start with a more common (but all manual) film camera (35mm or 120 medium format) and really get to know the film process. You should have no problem getting 35mm processed in most places still. This will help you understand manual settings and how they interact with film as well as some of the errors inherent to the process. In the long run this will most likely save you a lot of money and generally help you build into the 4x5. I say this mostly because I would hate to see you give up on film because the 4x5 ends up being expensive and cumbersome while the results are less than desirable. I learn by doing to messing with 35mm film in a cheap old nikon FT first helped me really learn how it worked before I went out and started playing with nice film cameras and shooting medium format (which I'm only now getting into).
If you have any questions feel free to ask
