If I can shove twopennywoth in..........Looking at item 'f' on page 11 of Andy McConnell's (Miller's) 20th Century Glass, the Borske Sklo piece 'looks' typical of Borske Sklo 'Olives' pattern (and my three pieces).....insofar as the 'olives' can be felt from the outside (and they are not circular). The picture of the LSA piece shown here, doesn't have the 'olives' look, and it doesn't appear that you could feel the edges of the olives. Although I haven't handled an LSA piece - this difference might be the deciding factor. This, of course is on the assumption that it is the 'olives' pattern that the LSA piece is supposed to be.
