this is The 8th king’s Royal Irish Hussars Sabretache

https://en.wikipedia.org/wiki/Sabretache

Yes these things are expensive

BRITISH 8TH (KINGS ROYAL IRISH) HUSSARS SABRETACHE.
Extremely rare and beautiful the sabretache dates from approximately 1840.
It is normally considered that pre Crimea sabretaches are of a large size,
the size of this sabretache is slightly smaller than the post Crimea sized sabretaches.
The 8th Royal Irish Hussars were formed as a Hussar Regiment in 1825,
it was not until 1855 that the Regiment was allowed to add the Battle Honours of Hindoostan and Leswarree,
these battles actually took place prior to them being formed as The Royal Irish Hussars.
The Regiment then won four further Battle Honours in the Crimea and two in Central India and Afghanistan,
all post Crimea, therefore this sabretache without any Battle Honours added can be dated at approximately 1840.
