kythri many thanks for bringing this issue to the front. your experience, as well as my own inspections convinced me this one was worth the buy even if it requires a restore in 3 years. I just paid $95 for mine and noticed that the surface finish out of the box is arguably the poorest quality of the entire vise. But since this is a chinese copy of an imported wilton

I'm not surprised -- I came to realize that what you are buying is a product which can be re-finished later, yielding a high quality vise in the end. Its rather like finding a 1745 with new jaws and only cosmetic defects at a yard sale for $100.
Slip_Kid many thanks for showing your disassembled Wilton; very helpful. I have some remaining questions I wasn't able to answer from reading here, with respect to the rear (female) screw assembly, which I assume is held by the pin(s)
1. how are the pin(s) removed, if needed?
2. how can the end cap be removed - is this simply a press fit that can be pried out with a screwdriver?
3. is the static screw assembly one piece that is removed out the end after the cap and pins are removed?
If curiosity gets to me, I might take mine apart just to inspect those parts more thoroughly (i.e. with a better view than one can obtain from the front). This area is pretty important, as it applies and sustains the clamping force generated by the lead screw.
