This is the original prism for the F3. It is smaller than the the HP model AND has a bigger view. Why would anyone want an HP? The HP is a longer eye relief, so you can see the whole frame with glasses on. If you do not wear glasses then this is the one that you want.
This one is in excellent condition with light wear. There is a small crack in the plastic on the switch that toggles the eyepiece cover but it does not affect the function of the prism. Otherwise there are no dents and clean scratch-free glass.
