mruss90, I can't tell you either if they are original or not, but judging by your pics, they seem to appear to be the same grips that they called 'old reproduction' in the other post. Seems to be the same pattern, coloring, and the backside looks the same. Looks like the originals have the flat ridge around the outside whereas yours seem to be more flat. Maybe someone will respond who knows about these old grips.
