"Early Russian Cuirassier Saber Hilts" Topic

Osprey tells us, in some detail, about the Dragoon model saber guard, and I think it's from Viskovatov.

However, the alternate web source, where we first learned of the rarity of the kiwer on Russian Infantry and Hussars, has this brief comment re early cuirassier sabers:

"In 1809, new swords were ordered for both guard and line in two models. (The 1806 dragoon pattern is an error.)"

So if that is in error, what were the cuirassiers carrying before 1809?

I am not an expert, but there is such information on the Russian Internet:

Since the 1700s, the following types of broadswords were in service with the Russian regular army:

Dragoon broadsword, officer, 1700s
Dragoon broadsword, officer, 1720s
Dragoon broadsword, soldier (2 options), 1750s
Cuirassier broadsword, 1740s
Broadsword of the Life Guards Cavalry Regiment, soldier, 1763
Cuirassier broadsword, 1760
Carabinier broadsword, soldier, 1763
Broadsword of the Life Guards Cavalry Regiment, second half of the 1790s
Dragoon broadsword, soldier and officer, 1798
Broadsword army cuirassier, soldier and officer, 1798
Cavalie Guards broadsword, 1799
Cavalier Guards broadsword (for wearing with a vice-uniform), 1799
Cavalier Guards broadsword, 1802
Horse artillery broadsword, for lower ranks, 1803
Dragoon broadsword, soldier and officer, 1806
Broadsword cuirassier, soldier and officer, 1810
Broadsword cuirassier, soldier and officer, 1826
Boarding broadsword, sailor, 1856

I assume that the mistake is that the sword mod. 1806 could be used later than 1809.
