Help with Clausing 5904 lathe

[Tim_Eickschen]

I may possibly be making a purchase on a Clausing 5904 lathe. After doing some research I have found that these lathes frequently have issues with the variable speed. I have not yet seen the lathe in person or have worked with one like this. Does anybody have experience with this lathe? And what do I need to look out for on the variable speed when I go look at this lathe in a few days?

Thanks
