Hi Jim.
The springs will be German, unless Smiths / Enfield British, and may be OK.
You'll need to clean all the old grease off - don't worry about them being straightened, apart from the inner coil or two.
Have a close look at the outer holes as it will those with splits if there are any.
Clock grease or car gear oil is fine - lubricate before fitting in barrel.
Strike and going train springs are usually the same, chime spring is larger.
Goggles needed!
If you need more in-depth advice, feel free to PM me.
