Description
This item is approx 10cm in Length and dates 1900's
It is triangular at the base with Brass encapsulating a reflective Triangular Glass?
The instrument is support via a Gold Looking(although NOT Gold) handle with a hole thru the crown.
I suspect it is a Builders Instrument of some description-perhaps to gain levels on a construction site.
Other than that it may have some connection to the Masonic Lodge.
