Yes, the mark does look the same.
The Nicholsons were in business between c. 1756 and c. 1830 with the partnership of John and Nicholas Nicholson in existence between 1797 and 1804.
Joseph Gibson was in business 1784 to about 1820.
However, the common use of this punch by the Nicholsons and Gibson may be connected to the fact that Joseph Gibson married a daughter of John Nicholson on 3 June 1788 and he may have been apprenticed to the same John Nicholson.
If so, it may be another example of the intermarriage of Cork silversmiths and a hint as to their business practices.
Very many thanks for pointing out this example.
