I'm unable to ID them although it seems to be from the Lynnfield series. In general, I'd say that that BA 3 way is worth checking out at that price although it would certainly be helpful to find the model if only to ensure no drivers have been replaced.
I saw those pop up last night, too. Model number is in the second pic. A22. Allegedly, they were a limited run export speaker. I've never heard a pair, but would expect quality along the lines of the early-mid 90's offerings.
