An interesting military spirit level.

We are assuming that this level is military based on its colour and the variety of markings.

There are two arrows within diamonds on the mounting plate plus 'AN32056' and '294'.  

Another number has been overstamped with crosses.

The adjustable level has a brass casing and is fitted in a steel mounting with protective cover.

The cover is marked 'AN32056'.

The bubble and tube are intact.

All parts move freely and tighten securely.

One of the cover screws is missing, please see images.

3⁷/₈ inches (99mm) by 2³/₈ inches (60mm) overall.
