Hub and brake drum
Front wheel hub and brake drum assembly for drum-brake front ends, also listed as W1325 in older parts books.
37-1325 is the front hub and brake drum assembly, the part that carries the wheel bearings and gives the front brake shoes something to press against. It shows up in the parts books under the FRONT WHEEL figures for T110, TR6 and T120 machines, and in the older parts book it was listed as W1325 before the modern numbering came in.

This is a combined casting, so it's doing double duty as the rotating drum surface for the brake and the housing for the front wheel bearings. Catalog listings for this part span 1960 through 1965, which lines up with the drum-brake front end era before Triumph moved to a front disc.
If you're chasing a hub for a front drum brake setup, this is the part number to check against your bike's wheel. Bring your old hub down or have your parts book handy so we can confirm you're matching the right drum to the right brake plate and spindle.
