a wiggle?

[B. Dudley]

Yeah... If that is the only issue there is, Buy that Gun!

But... if it is an internet seller and the gun is not seen first hand, the ammount of wiggle can be up for interpretation.

A lever left of center would indicate a worn out bolt or bolt bite. As the locking bolt and bite wear out, the lever will move over bit by bit. Until the wear is so much that the bolt starts contacting the lug on it's face instead of the tapered bottom as intended. This is when up and down movement starts to be felt.
If the VH is an earlier one (pre 1910 or so). It would not have the hardened and replaceable wear plate on the bolt bite. So it is more common to find these types of guns worn out and loose.

If the wiggle is side to side, then it is hinge pin wear.
