Well that’s a nice one!!! What a beauty!!! Congrats, I’m fond of cavalry!
Only the plume has a bit strange form I think, and the special Leib garde husaren fangschnurr specific for this regiment, with the tassels seems to be missing ( like most of those busbies as welll as mine, my leidgarde husaren busby also missing specific fangschnur) have a Dutch lookalike on it.
