The "incuse head" of the King hallmark would make this assayed in 1784 or 1785, and here is what I have found out according to Grimwade:
"Wren entered his mark as a spoon maker from 95 Bishopsgate Street on 27th February 1777.
He continued to be assessed to Land Tax on property in Bishopsgate until 1786. The property was empty in 1787.
His burial aged 41 years was registered at St Botolph, Aldersgate in 1786..
The Will of John Wren, late silversmith of St Botolph without Bishopsgate parish, was granted probate on 13th June 1786."

I have been confused with the John Wren II hallmark when compared with the other similar hallmarks, it is very difficult for me to figure this out, and also I have noticed a few people who claim to be selling "John Wren II" silver spoons, but the dates of assay on the spoons are after 1786, when it appears that John Wren II was buried, according to Grimwade :::
