It really is a specialty item made for Europe that some folks imported to the U.S.
No offense, but Pietta isn't in the business of selling "convertable" pistols. They are selling C&B revolvers.
They can't "disclose" everything that won't fit...
It would be valid to complain if the seller claimed it could be converted. but then you should take it up with the seller.
If one wants a conversion cylinder it really is up to the individual to perform the "Due Diligence" to locate it themselves-
looking at all the sites that sell conversion cylinders, one will rapidly see what "is" available.
If you don't see it, it ain't available.

That ain't necessarily the case. Often times I've Startpage Fu'd the poo out of something, settled for something second best, and in SECONDS after ran into something closer to what I wanted in the first place. I wasn't even looking for BP 1873s in the first place.
It depends on what any given search engine wants you to see, normally the companies that have paid the given engine highly.
