I apologize in advance if this has been covered before, but I've never seen this version of the L100T. The versions I'm familiar with are the L100T, L100T3, and L100S (vinyl covered version of the L100T3 sold to members of the U.S. Armed Forces).

While surfing ebay, I came upon this pair that are in Poland. The differences I see from the aforementioned models are:
  • A silver identification sticker on the backs with additional information
  • No trim rings on the ports
  • Metal JBL badges on the grills and cabinets
  • 4 grill guides instead of 6
  • What appears to be a much nicer walnut veneer
Just in case this hasn't been covered before here, below is the link to the auction and some of the its photos for reference.
