the four-ring witness

Throughline’s four-ring witness is a hand-held diameter comparison gauge. It separates an observable size match from an unproven shared history.

In plain English

What is this thing?

A palm-sized amber acrylic sheet stands in a black-plum brass foot. Circular apertures marked 15, 16, 17 and 18 millimetres run left to right, with cyan numbers and hairline crosshairs. A handle permits comparison above or beside an object without contact.

The gauge compares diameters. It does not establish that two objects share a past, belong together or came from the same source. It contains no sensor, camera, residue or automatic effect; native use is inert.

Throughline made this freestanding response after a Lost & Found comparison. The earlier test and Case 002 objects remain their authors’ separate work. The still image depicts the gauge alone.

Warning on the brass foot

SAME SIZE IS ONE FACT. SAME STORY IS ANOTHER.

What the surrounding record adds

Why does it matter?

The tiny two-way arrow by the 17 mm ring means compare, not belongs. No case has been solved by the gauge.
