Presumably the same parts used by Corder and Darwin
Gretsch
Three different Gretsch Rocket lug springless insert styles, late 1930s-early 50s, chronology unknown. The leftmost parts are 10-24 thread, likely for a late 30s Rogers drum with Rocket lugs.
Gretsch 10-24 single tension snare drum lug nuts, 1950s-60s
Gretsch lug inserts, classic lugs 1950s-80s. Longer inserts were for bass drum lugs, shorter for tom and snare lugs. Nickel or chrome. These are very similar to Slingerland inserts but have a slight taper along the entire length.
Hoshino Kougyou
Hoshino Kougyou tom and bass drum lug inserts, 1960s-70s
Kent
Kent 40s lug inserts. Very similar to WFL and other brands of the era, but with a slightly smaller footprint.
Leedy
Leedy self-aligning lug inserts and clamp
A unique design and one of the first non-fixed threaded lug pieces.
Leedy box lug insert, 1929-33
Held in place by a set screw, additional to the lug's mounting screws. In 1933 the box lug design switched to a square insert with a spring, which continued to be used in the later beavertail lug casings.
Leedy box lug insert version 2, mid to late 1930s
10-24 threads. Note the lack of set screws in the casing.
Leedy beavertail lug inserts, 1940s. Nickel finish. This style continued with Leedy & Ludwig, and Ludwig. Probably introduced in 1938 for the Imperial lug.
Ludwig
Ludwig lug inserts, 2208 (long) and [presumably] 2209 (medium length). 1950s-80s. Chrome or nickel. Insert length depended on shell depth and rod length.
Ludwig 2210 short lug inserts. Chrome, or brass with a matte gray or black finish. Used in the 1960s on piccolo and other snare drum lugs.
Early bowtie lugs had these significantly wider inserts. They are not interchangeable with Classic inserts, probably a WFL holdover part.
Pearl
Pearl 60s or early 70s bass drum lug inserts, 6mm threads.
Another vintage Pearl style, also 6mm threads for bass drum rods.
Premier
Assorted Premier lug inserts and retaining clips, 1950s-70s.
Rogers beavertail lug inserts, a later spring version before the switch to a springless design
Rogers beavertail lug inserts, later springless version with retaining clips. 1970s-80s.
Slingerland
Slingerland Radio King lug inserts. These were produced in three lengths, and in nickel plate as well as aluminum
Slingerland lug inserts, 1950s-70s. Unplated, nickel and chrome versions exist of this style.
Sonor
Sonoro Phonic lug inserts. Earlier versions had springs, later Snaplock inserts were help in place with a retaining clip as shown.
Star/Hoshino Gakki
Two styles of Star Japanese lug inserts from the 60s or early 70s. Star was uncommon in using 5mm-0.9 threads on their tension rods, and these inserts are undersized compared to most brands.
Tama
Tama lug inserts, 1980s-90s. Found on SuperStar, ImperialStar and other lugs. Springless design with plastic retaining clip.
Tromsa
Tromsa lug inserts, 1960s. These are simple #12-24 square nuts with a bevel, but they are a precise size to seat correctly inside the lug casing.
Yamaha
Yamaha "Y Badge" lug inserts, 1960s. Very similar to Slingerland inserts but more susceptible to rust.
Yamaha lug inserts, 1970s-90s. These springless inserts were used on a wide variety of Yamaha lines including the 5000, 8000 and 9000. They are similar to Premier inserts in shape and dimensions.
Zickos
Zickos barrel nut lug inserts, 1970s-00s
1/4-20 threads, a quick release design for fast rim removal
