Hello again. I was thinking the same thing. I bought it purely on the basis of "like the look of that" and it was some time later that I saw a sword that looked remarkably similar and was titled 1767 etc.  I didn't do any thorough research because it fell outside of my Shotley Bridge quest at the time. It was only when you posted your example that I began to give it my attention.
I've never really considered it a smallsword but it is, isn't it?  Albeit, a battlefield weapon rather than a civilian one.  The blade is superb, just stiff enough for penetration AND razor sharp.  It has a most curious cartouche with an even more puzzling motto that, so far, has defied translation.  It is identical on both sides.

If it is not a pattern 1767 then I can't imagine what it is… maybe it is just a sword, custom made to suit.  Regardless, I am very fond of it.
OK, enough of that, now the colichemarde: it is certainly a typical colichemarde blade but then again there are different versions of the groove.  Here are four, from my friend Mel again (he has specialised in collecting smallswords ) and in one case you will see the roller traveled right up to the ricasso.
