Well, I would think that the body style is irrelevant -- the one I had was spherical and bright blue with what was (at least then) the standard trigger/fuse arrangement on the top. With it, basically you pull the pin and the only thing holding a spring-loaded striker down is your hand pressure on the spoon (I think that's the right term). Release that, and the spring is enough to throw the spoon free and snap the striker through an arc to slam down on the top of the grenade where, presumably, a firing cap or fuse or something would be. And as long as you were holding down the spoon, it was trivial to re-insert the pin or another long, thin metal object to lock it down and "safe" the grenade again.
If grenade design has changed so much in 30 years that this isn't even close any more I'd be very interested in learning what replaced it.
