Rear wheel rim WM3-19
Rear wheel rim, WM3-19 size, for Triumph rear wheel assemblies, catalog PN 37-0270A (alias W270A).
This is the rear wheel rim for the WM3-19 size, the shape and diameter Triumph used out back on a number of unit-twin models. It's the bare rim only, the hoop that the spokes lace into and the tire seats on - not a complete wheel assembly. The catalog carries it under 37-0270A, with W270A as the older-style alias for the same part.

It shows up in the REAR WHEEL section of the parts books, and the catalog record ties it to the 1969-1970 span. If you're rebuilding a rear wheel from scratch, this is the piece you'd be lacing spokes into along with a hub and the correct spoke set - it doesn't come with any of that hardware.
Beyond the WM3-19 sizing and its place in the rear wheel figures, we don't have more detail on this one in our records. Confirm it matches your hub and spoke pattern before you order.
