Two types of wrist strap were available:-
A normal cloth type. Cloth straps were the standard type supplied with the camera rolled in a plastic cover. The original straps had sliding plastic black tabs to lock the strap into position. The later types had metal clips as shown below. It is unknown when the change took place as both types of strap turn up frequently.
Chain Strap. This was available as an optional extra. Much longer than the cloth strap it was available in a shrink wrap pack.
