From what I have been told, the 993's are a replica of the 441's which are quite popular. On the very top left of this screen you will see 'menu' and click on that and go to 'tool box' then under 'other programs' go to 'Casting Numbers' and look for the numbers you have and you will see the notes on each. The 993's are the only ones listed of the 3 you have.
