Teodor, bravo! You have memory size of British Library!:-)
Here is the my Tunisian sword described by Teodor.It sports a British dragoon blade second half of 18 century.
Also shown the original British sword with a similar blade but in its original garb.
Thom Richardson in his book " Islamic Arms and Armour", p.70 based on the collection of Royal Armoury in Leeds defines Tunisian swords as " very rare"
Not for nothing one with intact crossguard but without a scabbard was sold at Czerny's for 1000 euros + 28% premium.
