My interactions with modulus ended about 93ish. Up until that point as far as I know they only ever used one logo. If later on they started doing something different it is very possible. But I really don't think that any of phil's modulus could really be considered off the rack. He is always looking to tweak and perfect some aspect of something necessitating a new instrument.
