name of device to mark position of a model

[jesskramer]

Friends,

I am trying to remember what one calles the pointer like stick, usually on a stand that swings into place to mark the position of a subject's nose , or an actor's arm, etc.

Once in position the subject can move out and then can move back again in exactly the same position

I am sure I have heard what this type of device is called but it escapes me...any help appreciated

Thanks, Jesse

I've used C stands for this. Also, a barber's head rest can be quite helpful to position the head. Also, grease pencil on the ground glass can make the position very accurate.
