			It can be hard to tell the models apart. The 1833 had a smooth rounded quillion so this is one of the earlier versions with the lobed quillion. Without any markings the length of the blade may give you a clue. 
		
		
		
		
		
		
		
	Model IX 1800 Blade: 65cm long and 5.1cm wide at ricasso Model X 1801/2 Blade: 75cm long and 3.9cm wide Model 1811 Blade: 67.6 long and 3.65 wide These are much rarer than the 1833. David  |
