The Harcourt bayonet was named after Gen. William Harcourt ⁽¹⁾,  Colonel of the 16th Light Dragoons (Queens Light Dragoons).  It was designed to fit a carbine with a barrel of 3ft 1in.  Henry Nock a well respected gun manufacture of the period supplied 500 Carbines in 1794 at a cost of 50 shillings each.  This would suggest that only 500 bayonets would have been supplied.

The illustrated example is missing the distinctive basal locking ring (see the M1815 Baker Socket for a nearly identical locking ring).

A partial company/rack number is visible on the socket, 'C' over '4' or '7'.

Blade marking of the inspectors stamp of a 'Crown' over a '2'.   This appears to be a extremely rare inspectors stamp as I have seen no other British socket bayonet with this stamp.

This style of blade shoulders is very rare on British bayonets and closely reflects French blade design,  the only other British socket bayonets to use this style of shoulders are the Duke of Richmond and the M1815 Baker.  This style of shoulder less blade offers no support for the leather scabbards then in use by the Board of Ordnance,  It may therefore be that the scabbards used on these bayonets would have had a brass mouth piece.
