What is this mortar?

[Spitace41]

Hi all. Got this a while ago but have not yet found out exactly what it is or what age it is, does anyone have any ideas? The deact cert says it is a Brandt, the cal is 81mm, it is marked with the broard arrow and the serial number is 0005.

Many thanks.

South African 81mm M3 mortar...

Hi.
Looks like a South African 81mm M3 mortar, almost sure it is.
