Early 20thC Blackened Brass Binoculars – Military Issue?

Unusually these binoculars totally lack any makers details unless it is very well hidden under the black paint. The body is brass which has been blackened and the barrels are black leather clad, they are adjustable and the optics are very good and clear but would benefit from a strip down clean, they measure 6.5 inches closed and aside from general age use marks have a dent on one eye piece.
