Identify instruments used in Ravel's Bolero?

Question

I'm trying to identify the instruments used in each part of Ravel's Bolero. I'm hoping somebody can tell me which instruments are being played during each section of the piece. (Forgive my ignorance but I think the melody is played through 18 times, then it changes a bit at the very end when it sounds like elephants)
Here is my guess, please correct when needed and fill in the blanks
1-flute
2-bassoon
3-?
4-clarinet
5-oboe
6-trumpet
7-tenor sax
8-soprano sax
9-picolo + ?
10-?
11- trombone
12-flute + ?
13 strings
14-strings + woodwinds?
15-strings + trumpets + ?
16-strings + ?
17-?
18 - brass + woodwinds (or is it full orchestra?)
then the melody changes a bit and then sounds like elephants, then ends.
I'm hoping somebody who knows the piece well can tell me exacty which instruments are being playing and when. I'd like to play this piece for my kids as a listening excersize on identifying the sound of different instruments (but I need the lesson first! hehe)

I'm hoping somebody can tell me which particular instruments are being played each time through the melody. for instance flutes are played the first time through, then, Bassoon played the 2nd time through, the 3rd time through I'm not sure, then clarinet the 4th time through. Please don't spout off the wikipedia general info, and please don't answer the question when you don't know the answer and/or have not even read the entire question.

Answer 1

Boléro is written for a large orchestra consisting of two flutes, piccolo, two oboes, oboe d'amore, cor anglais, E-flat clarinet, two B-flat clarinets, bass clarinet, two bassoons, contrabassoon, four horns, piccolo trumpet in D, three trumpets, three trombones, tuba, three saxophones (one sopranino, one soprano and one tenor- one of the first large ensemble pieces to employ the family), timpani, two snare drums, cymbals, tam-tam, celesta, harp and strings (violins, violas, cellos and double basses). An average performance will last in the area of fifteen minutes, with some recordings extending as long as 18 minutes. The original version by Ravel took 17 minutes 6 seconds.
