Gerald Mohr/Mr Fantastic - 'Faster Than A Speeding Bullet'

I know that Gerald Mohr did the narrating task for The Lone Ranger, but I always thought that the guy who does the introduction to the George Reeves TV series ("Faster than a speeding bullet...") sounds a lot like Gerald Mohr, also.

I didn't see the credit on imdb, but it does sound a lot like the Lone Ranger narrator, as well as Mr Fantastic. Any insights, True Believers?
