How to unlock the The Nose Knows achievement in L.A. Noire - Definitive Guide
The second officer points the right clue (metallic bin-like cylinder) which once inspected, you just have to align the letters for the clue to count and achievement should be yours.
At the beginning of the case, after taking care of the looters, you will be asked to search for clues at the Explosion Site. To the left of the coroner there will be a path that forks. Follow down the path right to the end until you see an officer who tells you to inspect the metal pieces to his left. Complete the clue by lining up the bottom and top pieces of the prop spinner till it reads "P&W WASP MAJOR R-4360." Once you've lined up the pieces of metal the achievement will unlock.
Case: Nicholson Electroplating [Arson]

*Missable* This trophy is earned by properly assembling the aircraft part discovered at the scene of Nicholson Electroplating. To find the part simply take the rightmost path while investigating the blast scene. The right side path will turn right a second time, as it curves slightly back upon itself, and the large metal part is easily found upon the ground there. Aligning the pieces correctly unlocks the trophy.
We arrive at the scene of the explosion. There are only three places with evidence there. If it's difficult, use your intuition. A uniformed cop will be hovering near the evidence we need and will point out some round steel parts that need to be connected correctly. We twist until the letters fit correctly into “P&W Wasp Major R-4360” and we get the first trophy in this matter.
*PS Puzzle with a cipher: set “H” on the large ring, then “K” on the small one. Then we turn only the large ring, stopping at those letters that come after the number 133 in the circled text. The result will appear at the top left.
