While I suspect most here have already seen it, Count-General Stanisław Szeptycki's purported eagle-head saber is up for sale. Starting bid is 36k PLN, so around 10k USD. I was a bit surprised to see the inscription etched rather than incorporated into the blade design, which seems to have been the standard for such important sabers.
In any case, I've attached the auction photos for everybody's interest. Debate greatly welcome ;-)
