Apple 922-7075, 922-7245, 922-7751, 922-7832, 922-7651
This is the stand for the 17″ White iMac. Apple lists each model with a different part number, but as near as I can tell, they are the same except for the printing on the bottom. So my guess is that this stand will fit at least these iMacs as they use the same basic housing and clutch:
iMac G5 17″ iSight
iMac 17″ Intel Early, Mid and Late 2006
This has a couple of small nicks on the top of the front of the base.
