I think there may have been a thread or two about this seller at the old place. What truly boggles the mind is that not only do people buy this seller's stuff, but (s)he has
100% positive feedback.
Thing is, the only way to hold a seller accountable for this sort of thing would be to buy the item and then post negative feedback. Even then, most of their item descriptions don't have actual false information. The bells are "hand hammered", after all. That convertible tenor/alto is a different case but, even on that horn, the wording is such that "intent to deceive" isn't entirely obvious.
...one that tunes the instrument to a high Eb
It looks like the short tuning slide probably raises the pitch about a 1/2 step. That would raise the D above the staff to an Eb, so someone could (very) loosely interpret that as tuning the instrument to a high Eb.
Now as to the instrument being sterling silver? Particularly the tuning slide? Doubtful, but the seller could simply be "mistaken".
