Okay, so I've been trying to get all the items to appear at the guildmasters desk in the cistern, link to the quest: http://www.uesp.net/wiki/Skyrim:Thieves_Guild_%28faction%29#Larceny_Targets , the first 7 you just find on the thieves main quest, the remaing 8 you should get doing additional jobs for Vex and Delvin.

If tried it several times to complete it, but I never get the jeweled flagon(75jobs) to appear, and neither will the safe(125jobs).

So now I'm wandering if anyone did manage to complete this, and ofcourse how?

I finally got it on my 4th attempt, all 15 items are there now... somehow the safe even appeared this time round.

still have to get the crown, but that's an other quest.

the larceny items did have a few problems however:
- delvin never took the left eye in, had to put it there myself. (known bug w. handing in last larceny item)
- larceny items tend to drop from the shelves, puting them back they will just be dropped again the next time you enter, or sometimes dissapear completly.
- gray fox bust will drop at the slightest toutch, hard to put back standing up. in the image you can see it floats above the desk...

and the other items from the jobs:
- jeweled flagon (75jobs) never appeared.
standing in the cistern after doing the well more than the required ammount of jobs, I had to console: "prid E8F04[enter]" and "enable[enter]" to make it appear.
