The "IB" maker's mark is a very common
mark. We therefore cannot be at all certain of the attribution of any
particular mark to John Blake. However to the best of my belief all of
those shown below are John Blake's marks. Click on any picture to enlarge |
1786 - 1790
(notice the flaw in the punch - a tiny vertical "cut" to the right of the "I")
1791
(notice the flaw in the punch - a tiny vertical "cut" to the right of the "I")
1792
(notice the flaw in the punch - a tiny vertical "cut" to the right of the "I")
1794
(notice the journeyman's mark alongside the maker's mark, and the now familiar
flaw)

Blake)
