it is engraved with original clyburn no.1 and has a serial number on it
is it a serial no or a patent no?that way you may be able to identify it.

Ironically, the No 2 is also engraved "The Original"
It would be interesting to see what number is on yours, I have never seen a reference to an actual patent number, tho everyone seems certain of the invention date (how?)
-
i think the original is on all clyburn spanners whatever number they are,
-
done some googling,found that the patent date is said to be-15th oct 1843.no patent number yet.

This is why I don't trust data from the net, when everyone knows something, but nobody can give a reference ;P
There were no Utility patents issued Oct 15, 1843 whatsoever.
There was a patent issued to Richard Clyburn on Sep 5th , 1843 however.
(Note: 1842 on the table is a typo, the succeeding tables are dated 1843, in sequence, and it is from the 1844 register, which is likely where the 1842 claims come from)
From: The Mechanic's Magazine, Museum, Register, Journal and Gazette, Volume 39
(google books)
PS: The actual patent number is 3

is that your anglophobia rearing its ugly head again crusty?

Just dataphobia ;P
I have also seen Sep 13 claimed ....

here are some photos of the clyburn spanner

I'll wade in a bit -- the Sept. 5, 1843 Richard Clyburn "design" patent & provisions of the pertinent British patent laws was noted on pg. 4 of the June 2010 MVWC Newsletter. That bit was copied from "The London Journal of Arts & Sciences" which google had digitized from Oxford University's Library collection.
The CLYBURN design was kept in production for a long, long time -- the lettering style on the example pictured looks 1920-ish (sorta like the lettering on the WAKEFIELD WIZARD and other 1920s U.S. wrenches).
