It’s looking to me like Ludwig made all their brass shelled snares in the “Double Bead” center rib (2 piece, 4 seam with the double thickness in the center rib) until some time around 1930 (in The USA the Great Depression was starting). The exception is the “Junior” model that they possibly introduced sometime in 1925, but it definitely was in their 1926 catalog.
It seems that the “Junior” model might be the first metal shell to have the single seam and thinner center rib.
When the “Universal” model appears for the first time in the 1924 D catalog, it looks as if it was issued with the “Double Bead” center rib at that time.
The 1927 catalog has a good description of the “Double Bead” shell, although the cut away image of the shell looks to have a vertical seam all the way up through both half pieces and that is more like the 1 piece shells (probably just the art department’s choice of images back then).
The 6 lug “Pioneer” seems to first show up in the February 1928 catalog and although it is left out of the September 1928 catalog, it re-appears in the 1929 catalog, and is described as having the “double spun bead at the center” in that year. Meanwhile the “Junior” model continued to be the only one pieced thin center rib style offered. The “Universal” model is out of the 1929 catalog though. The 6 lug “Pioneer” and the “Junior” continue to be offered in 1930 without change.
By 1932 the Pioneer is now offered as an 8 lugger and appears in that catalog with what looks like a thinner center rib similar to the “Junior”.
In 1933 after five years, the “Universal” returns with 8 lugs and the better strainer like on the “Pioneer”. The “Pioneer” shows up in 1933 with the vent hole now in the closer position to the strainer and with a badge around the vent.
By 1930 Ludwig didn’t seem to be mentioning the “Double Bead” construction in their catalogs anymore. I’ve only seen the Ludwig catalogs available at The Vintage Drum Guide so I may not be aware of some things, but I’m hoping this log can help to identify some of those 20s Ludwig brass shelled snares out there, and get a good timeline date for the heavy shell/thinner shell evolution. There are other parts changes and details that we can use to get a narrower date ID on some of these snares too.
The “Double Bead” center rib shells had a whole lot of brazing and a double thick center rib so that would definitely add to the weight. I wish we could use a micrometer on the shells we’re familiar with to get some real sheet brass gauge info.
Feel free to help me correct this log, and please if you have examples of these drums, post good photos to confirm what those old catalogs presented.
