I think it will model 154, full advert
In reply to 153. The 154 was solid by bobbee
The ad I posted specifies the model number.
Imagine an ad saying "Clipper, in yellow or white" but the yellow is the 'A' variant, and the white model is actually 'B' variant, O.K.?
Your ad is just like my "Clipper" example, it shows there is solid and filled but gives just one variant.
Let's see if I got this right. In another 1924 model 154 record, admin lays out the following below:
14K solid; 18K 25 year (filled); 19K 25 year (filled) = 154
14K 25 year (quality filled) = 153
1923 Ad snippet model 154 1923 Ad snippet (153 154)
Jabs did the red circle above. In the other 1924 record, we accept the "In 18Kt. 25-year" in first 1923 ad refers to 154.
We do the opposite for the "Bulova Quality filled" in the red circle in 1924 ad. We don't accept the "Bulova Quality Filled" refers to the 154.
I don't believe that the distinction is correct.
We see also in the ads "25 year" regardless of gold karat content for gold filled.
This shows that "gold filled" or "quality filled" would be the 153 whatever the karat used, and 154 is for the solid gold models alone.
