A few years back I bought this Takara Microman "Rumble" Mini-cassette. It originaly came with the Microman version of Soundwave that was called MC-10 "Cassette Man". But instead of having blue upper-arms like this version, it had the common red upper-arms like the G1 Rumble. It has seen better days, and is missing some decals. But the rivets that connect the upper with the lower-arm look original and have no signs of tampering in any way. DOES ANYONE HAVE ANY INFO ON THIS VERSION? You must know that I own every Mini-cassette. Microman versions, G1 sticker and print versions and all 80's knock-off's or otherwise. So i know it's not a knock-off and i hope it's also not a custom. If you know, please let me know.
