I cannot find any reference to marlin ever making a model 226.
Yes the Marlin Model 1894FG is chambered in .41 mag.
Marlin did not produce a model 444 rifle with a saddle ring. The saddle ring was more common on lever-action rifles like the Model 336 or Model 1894.
No.
Can't give a very specific answer without make, model, distinguishing features, etc.
I can't find any indication that they made a 30-06 lever action. I can't find any indication that they made a 30-06 lever action.
No.
it was made from 1960-69 with a 24 inch barrel.
Yes, The model 41 was made by Marlin. It was based off of their model 101.
Marlin, currently owned by Remington, produces lever action and bolt action rifles. They probably could make you a pump action .30-30 but it would be unlikely that you could convince them to do this as a custom job unless you offered tens of thousands of dollars to possibly re-chamber a Remington 7600, modify its magazine to hold and feed the rimmed cartridge and stamp it with Marlin markings. You would do better to go with lever action...that is the action the .30-30 was designed for.
Marlin made a model 98 semi-auto .22cal rifle from 1957-1959.They also made a model 980 bolt action .22cal rifle from 1962-1970.They did not make a model 98 bolt action rifle in .22caliber.
That depends on the exact make and model of the rifle.
You do not want to do this. If it needs repair send it to the factory or a factory trained tech. <><><> There is more than one make and model. You need to contact the maker of YOUR rifle and get the owner's manual. A Winchester is very different from a Browning, which is different from a Marlin. And you did not tell us what make and model of rifle you have.
