Help with Hobbleskirt ID

[SODABOB]

Hi, again

Even though I am still hopeful of eventually hearing from Ivybriana, I thought the following might be of interest. I spent several hours searching for a Graham 576 Graham Hobbleskirt that had a heelmark with the letter 'R" to see what it looked like. Unfortunately, I could not find one. However, I did find several references for them, but no actual photos of the "R" mark. As a consequence, I went back to the Lockhart/Porter articles where the "R" is shown. As stated in the snippet in my last post, the "R" was modified from the letter "P" - which means it was originally a "P" with the 'leg' of the "R" added that apparently changed it from a 1916 date code to a 1918 date code.

My primary reason for this new post is to compare what appears to be a "P" on Ivybriana's bottle to the "R" on Bill Porter's bottle. Even though the Porter photos are not that clear, you can see part of the 'leg' on the "R" in both photos. Now compare it to Ivybriana's mark. Even though I can't say for certain, I don't see a so-called 'leg' on Ivybriana's mark. If it is a true "P" and not an "R", then we are back to the possibility that it is indeed a 1916 date code. (Maybe?)

Note: I converted Ivybriana's mark to black & white with the hope it would clarify it.

P.S. / In search of ...

During my search, the ONLY patent 1915 Coca Cola bottle I could find that was described as being marked with the "576 EP" heel code was a bottle from Gary, Indiana. Unfortunately, there was not photo of the mark. So, I can't say for certain what it looked like or if it was legit. However, if anyone who reads this has a patent 1915 bottle from Gary, Indiana that has the "576 EP" please share it with us.

Thanks

Bob

I found another Gary, Indiana bottle - this one was described "576 ER" - but not a very good photo - if accurate it would be a Graham bottle from 1918

the bottle marks in your 2 pics look different than the original Pic. In original Posters pic the E looks more like a backwards 3, your examples dont. Also her P seems to be same height as the E & 576, your examples the R looks smaller or shorter. like a different mold all together & not a modified mold. Just my 2 cents? LEON.
