ok, i still have my original soundwave. he's an old favorite, and i'm starting to try to restore hm. i just got a junker sw off ebay, and eagerly tried to perform a head transplant operation. the peg from my original was broken 25-odd years ago, and the head long since lost. anyway, i discovered that the hinge/peg/neck piece from the junker is larger than the one from my original. much frustration. then i noticed that my old soundwave has a takara stamp inside, whereas the junker does not. so, are there variations on the g1 soundwave? mine is a pre-rub, and apparently takara made, '84 model. the junker seems to be a later-made version, but it has no door, so i can't tell about it's rubsign, and there's no takara or hasbro marking in the same location as the other has (inside the 'battery compartment') any advice and/or production knowledge is appreciated.
