Don't worry about asking for help. Some of us LIKE playing "name that figure/part". (Some of us are even good at it.)
i've never tried the parts identifier here, only the figure identifier.
Did you get your questions answered? You can tell me if i got these right:
A1: G1 Swoop's wing-mounted missile launcher (color variant? Diaclone?)
A2: G1 Swoop's (or Diaclone's) other wing-mounted missile launcher
A3: G1 Jazz's shoulder-mounted missile launcher
A6: G1 Topspin's pistol
A7: G1 Tracks's missiles and missile mount
A8: breastplate for G1 Superion (combined form of G1 Aerialbots)
B2: fist of G1 or G2 Starscream or other G1/G2 Seeker
B4: G1 Soundwave's "missile"/gun barrel
B5: G1 Jazz's pistol
B8: shoulder-mounted missile launcher for G1 Red Alert or e-Hobby exclusive G1 Clamp Down*
B14: missile from G1 Red Alert or e-Hobby exclusive G1 Clamp Down*
*G1 Sideswipe and e-Hobby exclusive G1 Tigertrack have the same launcher with a different-colored trigger/tab; e-Hobby exclusive G1 Deep Cover has a blue launcher. i think only Japanese releases have springs strong enough to actually launch the missiles. Red Alert and Clamp Down have red missiles; Sideswipe, Tigertrack, and Deep Cover have white missiles.
