Piece Identification, 3x6 white horizontal cylinder I have these 4 white pieces from a large lot of pieces I purchased. Any idea what set they may be from? Most of the other sets have been Batman, Superman or super heros.
These appear in 4s in many iterations of the Imperial Shuttle, and also many of the X-wing, as well as the 
MT-201 Ultra-Drill Walker and the SP Undercover Cruiser. I can't say for certain which of these sets originally contained those pieces, but this should get you closer. This list also shows sets that contain the piece in smaller quantities.
