Identify items bought from market

[mxnster]

Is there any way to identify items bought from market?

The only idea i have its to get float from inspect link (using fload and etc) and compare, but it won't work for all games and skins.

Object of purchased item from market history:

Hi, you can match them by 

instanceid

[Dr. McKay]

classid and instanceid are not foolproof ways to match item instances. I'm not aware of any way to match an item from the market to an item in your inventory.
