A belt buckle with the Finnish lion symbol. Used army issue.
It will fit most 5 cm (2") webbing belts. Will also fit the US trouser belt, though does not look as "full" as with a wider belt. The Mil-Tec quick-release combat belt works just fine with this, see the extra pic.
Made of blackened brass. Quite often worn a bit, which only adds character.
Used, but in serviceable condition.
