Pair of early WH (Heeres) Panzer Eisenbahn Armoured train gunners slip on cyphers

This is an attractive and fully matching and with certainty scarcely found pair of early war and neatly cyphered WH (Heeres) panzer wrap pattern Eisenbahn Armoured train gunners shoulder strap slip on cyphers, made of the black coloured wool and has pink 'E' cyphers machined to each one. (see attached pictures)
These were specifically intended for and clearly used by a soldier who served within an armored trains related unit and that comes in an overall very nice condition.
