wasn't really a question - what it was has not been in doubt with me, just the auction house.
consider it rhetorical. along with the khyber i was having a small dig at the level of expertise. oddly they also sold in the same auction a number of 'yataghan' bayonets that sold for more than my yat did, so they are familiar with the term.
my khyber knife has a very slight but noticeable s-curve to the spine, not noticeable in it's photo but more apparent if you lay a yardstick on it.
it was referred to as a salawar yataghan in an earlier thread where i'd posted it by one of our esteemed colleagues here.
photo of my integral bolster karakulak yat/bulgarian shepherd's knife from a dealer in varna also attached for comparison.
