Narrative:

Nose gear failed to extend on approach. Went missed approach and vectored about 20 mi northeast of airfield until gear manually crammed down. Declared emergency on final with gear down and locked as precautionary action. Probably should have declared emergency initially when we went missed approach when problem discovered.
