Head over to the thread in "Tools" and follow the links I posted there. Also check maskinisten.net, the forums, and do a search for your machine there.
Another thing (I picked it up from Practical Machinist, which is another forum you can search. But don't join and post before you have read alot there, it has rather stringent rules, ask Andrew). Can you post a FULL front and one side of your machine? Makes it easier to identify for us...
