Yep, Bottecchia decals are what they (now) look like to me, too...but I don't think this is a Bottecchia frame, just some decals somebody slapped on.
The BB shell might be one of the early Cinelli investment-cast shells and the builder may have brazed a plate over the area where the cast-in Cinelli logo was. That's a treatment I've never seen done before, and the numbers don't tell me anything except it's a 57cm size.
Still mysterious, but it's clearly a good Italian frame so no reason not to enjoy it (in all its anonymity).
