Chevrolet Symbol/ Moniker use dates

[TangoBravo]

Does anyone know the years of use that Chevrolet utilized the Chevrolet bowtie with the short bars above and below the "CHEVROLET" name? I have seen indications that is was started early in the 1960's and probably stopped in the early 1970's What emblem/moniker replaced it, and when did Chevrolet cease using it?

This help?  They have a time line when various logos where introduced and phased out.

Thanks Hans for a good start. Didn't realize this particular design went back to 1913. Seems that they kept using it at later dates--some what sporadically.
