Copy Data No Duplicates

[mack22]

Hi Guys
I need to update data from Workbook 1 to Workbook 2 just needing to have the new rows to come across and not duplicating
Workbook 1 looks like this

stock no	model name	year model
a005013	911	2003
a005012	911	2003
a005011	911	2005
a005010	911	2005

<tbody>
</tbody>

Workbook 2 looks the same but needs to have the new stock no's added to it each week, so workbook 2 would also need to have stock no a005011, a005012 and a005013 when command button clicked

stock no	model name	year model
a005010	911	2005
a005009	911	2003

<tbody>
</tbody>

Thanks

I am not certain of the workbook names and don't know the worksheet names, so I have written this for two worksheets in the same workbook. Hopefully you can adapt but if not, post back with the above details.
Test with copies of your workbooks.

Sub Update_Table()
  Dim ws1 As Worksheet, ws2 As Worksheet
  Dim d As Object
  Dim a As Variant, b As Variant
  Dim i As Long, j As Long, k As Long
  
  Set ws1 = Sheets("Sheet1")
  Set ws2 = Sheets("Sheet2")
  Set d = CreateObject("Scripting.Dictionary")
  With ws2
    a = .Range("A2", .Range("C" & .Rows.Count).End(xlUp)).Value
  End With
  For i = 1 To UBound(a)
    d(a(i, 1)) = 1
  Next i
  With ws1
    a = .Range("A2", .Range("C" & .Rows.Count).End(xlUp)).Value
  End With
  For i = 1 To UBound(a)
    If Not d.exists(a(i, 1)) Then
      k = k + 1
      For j = 1 To 3
        a(k, j) = a(i, j)
      Next j
    End If
  Next i
  If k > 0 Then ws2.Range("A" & Rows.Count).End(xlUp).Offset(1).Resize(k, 3).Value = a
End Sub

Workbooks are called workbook 1 and workbook 2 and sheets are both sheet1 as not to complicate things.
