My 1930 model a has been sitting for 50-60 years, so today
I pulled the starter to check if it still works.
And it does, now my question is what do I look for further?

I also so that there where numbers beside the spring (picture 1)
What are these for?

And picture 2 is there an adjustment for the screw with the spring, ore is this just to let the screw touch the worm?

This is also my first model a where I am working on so in advance sorry for the dumb questions if they are dumb.

Mechanical handbook will be orderd in a few weeks, just disassembling parts so I can order everything at once.

friendly greetings from "sunny" Belgium

The teeth of the gear on the worm shaft are a little demolished, can I just clean the rough edges and leave it for know?

I am not going to do a full rebuild of this car, just make it run once more
 
I would start by making sure the bendex bolts are tight, and check for tight bearings, by moving the shaft up and down.

I wouldn't, you run the risk of chewing up the ring gear or getting the drive bound up due to misalignment of the teeth - Compare your Bendix to a new one to see how bad it is.

Bendixs aren't terribly expensive.

The bearing has no radial movement, but when I pull the bendix to the left like if it is lying on its side like on picture 1 then the bendix slides nearly 1cm over the long bolt. Is this normal?

Should I go for an modern model a starter drive?
 
I would just replace the worn parts on the existing bendix. Also you might want to check the starter brushes.
 
Smooth the bendix teeth with a file, brush a LITTLE heavy grease on the flywheel teeth & it'll last for YEARS! I did this MANY times, on pre-1964 Jaguars!

How much do you want to spend? Running starters are cheap. They are extremely durable and can be purchased for as low as $10. They are so durable they say you can drive a mile on the starter before you cook it. Just stick it back in and enjoy it. If it were ever to die you can easily push start your car so don't worry. It's very important you clean the mating surfaces at the flywheel housing for a good ground.
 
You can remove the starter band to inspect the brushes. The 2 ground brushes usually wear out twice as fast as the field brushes, and they can be changed by just unscrewing 2 screws. If the field brushes need to be replaced, you will need a good size soldering gun, like a WEN 250 to solder then to the field windings.

I would put a couple drops of oil on the drive end plate, so it works into the bushing.
Your Bendix spring looks to be in perfect condition. The pinion teeth show some wear, but I would give it a try. If it does jam in the ring gear, then shift to high gear and rock the car forward. If the pinion need to be replace, maybe you can find just the pinion, rather than having to buy the complete starter. Or, you might buy a complete starter drive with a bent spring, and can use your spring on it. If you bend the lock tab just enough to remove the bolts, you should be able to reuse them a couple times, but if in doubt or you feel the tab is a bit weak then be sure to use new locking tab washers on the drive.

Use a small mirror to inspect the ring gear on the flywheel.
 
There is one longer bolt of the 3 that attach the starter to the flywheel housing it goes toward the steering column. If you put it next to the flywheel you will create a knock that wasn't there before.

Actually all 3 should be the same length, but sometimes people mix up mounting hardware when they have things apart. My early 1928 Parts Price List calls for 1" long bolts.
