I picked this one up last week. The prior owner had all the pieces in a box when I purchased it without any heads. Eight of the twenty rim clips were broken, the shell and rims were extremely dull and the t-rods, strainer and snare butt had so much rust on them they were barely recognizable. You can see pics of their original condition in the "Vintage Drum" section of the forum under the subject title: "NEED HELP TO I.D. THIS OLD LUDDY."
From the research I've done, this particular model was labelled "The original Ludwig all metal drum" and was offered between 1928 and 1936. It features 10 tube lugs, rim clips and the "Professional Strainer" (1928-1939), which was a revision of the Ludwig 338 strainer. Although the upgraded strainer included an extension lever, it wasn't included with my particular drum. You can see the hole in the upper portion of the triangular frame of the strainer where the extension lever would mount. Engraved on the shell of the drum is "Ludwig Trademark". It can be seen on othe panel just to the left of the strainer.
The finished product shown in the pic is the result of a lot of "elbow grease" using Cape Cod Cloths and "Evapo-Rust." I replaced the broken rim clips with some originals I had in my parts bin. At the present time, some are nickel and some are chrome. Hopefully, in the near future, I'll have all matching clips. I installed a Ludwig 100th Anniversary batter side head on the shell.
I'm very satisfied how this one turned out. It's one of the oldest drums in my current collection.
THANKS for looking!
