Surely a rare thing to see: https://www.ebay.co.uk/itm/Bang-Olufsen-B-O-EK2-Echo-Unit-Vintage-Early-1960s-RARE/112995132660?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
Sadly it doesn't fit my Grand Prix 610K (would have bought it right away if it did!).
I never saw this version, only the latter one, matching Grand Prix or Master de Luxe 610.
Nice find
