vintage folding bicycle/motorcycle tool, often called a multi-spanner or folding wrench set.

It contains:

2 ring spanners (box-end wrenches)

2 open-end spanners

Riveted together so they fold like a pocket knife.

These were commonly supplied with:

Older bicycles (1930s–1960s)

Mopeds

Small motorcycles

Agricultural equipment

The heavy steel construction and simple riveted design suggest it is probably mid-20th century (around 1940–1960).
