Yeah, $55 for shipping is silly. Maybe they meant $5...
Those Phillips head intonation adjustment screws don't look right either... of course a bridge rebuild kit would fix that.
I suppose it could be a knock off, but even for a Fernandes, that bridge is a darn good copy. Come to think of it, I don't recall having ever seen a 5-string Fernandes to compare with.
I've never had a reason to price a replacement bridge for an Alembic, so *strictly* an uneducated guess on my part - that $225 price is a little high for an incomplete used bridge, and a (probable) shop-night tailpiece.
