There was just recently a bunch of Carcano carbines imported from Ethiopia, both TS Carbines and Cavalry. I got a '91 TS from Palmetto State, pretty good condition for being stacked in a big metal shed for decades. I would think finding a lose bayonet for a cavalry carbine wouldn't be easy.
I hymned and hawed over those, I think when you linked to them

a while back. Classic FA has then now for $269 99.
I decided to pass Already loading 30/40 , 303 British, 30/06 , 8 × 51 R Lebel and 41 Swiss Vetterli
I just figured 6.5x52mm Carcano was some over reaching

However, the Carcano at the Gun shop is very affordable, bordering on " buy it you fool ! "
Even if I bought an original $49.50 bayonet from Sarco for it , it would still be under $200
