So far it appears that way. So more than likely only one glass company made these bottles for Joyce.
Which leaves a very limited number of bottle examples even produced.
I take back what I said earlier about them being error bottles. Based on the latest clues it appears Joyce Products intentionally ordered the white and orange variations from Reed Glass. Its doubtful that two variations would have been an accident.
I have been looking around but cannot find a definite answer to your question. However, I suspect they were more along the lines of being specific to Joyce Products in that they were ordered that way from the glass manufacturer to distinguish Joyce 7up bottles from those of other 7up bottlers. Even though this was fairly early for 7up ACL bottles (1937-38), a lot of bottlers were still doing their own thing and using amber bottles, such as those from San Diego, California and various locals in Texas that also used amber bottles. But I still have to believe the Parent Company would have frowned on any bottler who took it upon themselves to produce an ACL bottle with either a solid orange or solid white swimsuit on the label. I think if that sort of thing were allowed that we would be able to find more examples of the bottles and not just those by the Joyce Products Company of Columbus, Ohio.
Glenna (Stengel) Joyce had no substantive affiliation with either Ohio State or Notre Dame. A native of Greenfield, Ohio, she was a seamstress before her marriage to William H. “Will” Joyce, who move to Columbus, Ohio, in 1910 and, with a partner, established the Wyandotte Pop Co. and the Millbrook Distillery.
Will Joyce later started the Joyce Products Co. and Beverage Management Inc., which developed a lemon soda that became 7-Up. The Joyce's eventually owned several 7-Up bottling companies in Ohio and Michigan. After Will Joyce’s death in 1934, Glenna Joyce moved from a residence near Ohio State’s campus to Upper Arlington, Ohio, where she was a parishioner of St. Agatha Catholic Church. She was the major shareholder of Joyce Products Co. at the time of her death in 1960.
I found this picture of what appears to be your identical bottle. I found it on a website called Picclick.com that is one of those alternate sites that take you to eBay sales.
Does the background look familiar and is this possibly the picture that was on eBay when you bought your bottle?
Earlier I accused the Reed Glass Company of being a rouge. I take that back and draw your attention to the Joyce family who, after reading this article, I'm inclined to think were downright crazy. You won't believe it unless you read it for yourself, which will require having to save it to your files first where you can then zoom it. The names are a little hard to make sense of because of the dates and various Juniors, etc., but its definitely about the Joyce's and their entire family of 7up bottlers. Just suffice it to say that its a "dynamite" article! Check it out!

The St. Louis Dispatch ~ St. Louis, Missouri ~ December 23, 1979
I cropped this portion of the 1979 article to draw attention to the names and hopefully make sense of them. Some of the Toms, Williams, and Bills that are mentioned as still living at the time of the feud are not the original Joyce brothers who were born in the 1800s, but are sons, nephews, and cousins.
