date these Zenith brochures?

[3Guncolor]

The chassis sure looks like the 29JC20 on the first Brochure. Could be the first year 1962. Somebody needs to look up the model numbers to tell for sure. They are before 1965 for sure. Also take a look at the remote on the first Brochure I didn't know the older style were used with Zenith color. Never had a customer that still had one of them with the set.
