 I think that whoever wrote the ad copy of the first ad simply made a typo, the description of the sets mentions "37-690 DeLuxe but the caption under the photo does not. There was a standard version of both the 37-116 and 37-675 that came without the teledial, hence models of either set with the teledial were the so called "DeLuxe" models, but all 37-690s came with the teledial so calling one a "DeLuxe" would be redundant since there was no standard version.
