Lynard,
Here is a good link on lathes with alot of makers in it.

The Boxfords were copies of the SB 9", yours being a "heavy 10" or 10L is a bit heavier duty. Parts bring good dollars on ebay so don't throw it out, parts are also easy to find on ebay if you want to run it again. Good luck, and see you at the SB10K group. Oh and one other thing, get with Tony and have him add some pics of your turret on his lathes uk site since we haven't seen any over here....Bob
