Jaques St George small-club set c1850

I believe this is a St George set made by Jaques, based on the similarity of the pieces, most notably the knights and the royal pieces, to known stamped sets (see Jon Crumiller's example).

The bishops are deeply tulip-like, similar to another smaller St George in my collection.  That set also carries a tentative Jaques attribution, owing to the close similarity of its knights to those of a known stamped set.

And that is the second time I have mentioned stamped sets. This set is yet another of those frustratingly tantalising "hint-of-a-stamp" examples, with a faint mark on the white king. It may, of course, be nothing more than an incidental blemish, albeit one that happens to be roughly the right width for a "Jaques London", or perhaps even a "J. Jaques London", stamp. There seems to be the suggestion of a "J" and perhaps even a "U", but beyond that it becomes a case of Martian canals, with the eye all too willing to conjure a ghostly "Jaques" from the faintest of traces.

Another feature of note in this set:  in all of the other stamped St George sets that I have seen, the rooks have smooth bodies.  In this set, the rooks have concentric circles engraved up the bottom and main cylinder (again, similarly to my aforementioned small set).  And, very interestingly (okay, to a collector), this matches the Jaques pattern book , which also shows similarly engraved rooks (photo from Mike Darlow's excellent book "Woodturning Chessmen")

Kings stand a very small fraction over 4".  Boxwood and ebony, unweighted.
