Hi. I’m helping out some friends who found some old B&O products last week. The following products was found in ORIGINAL packaging and the Beogram had never been opened before last week! I’m trying to price it as a lot - how would you price these new old products (never used):   Beogram 4000 incl SP15 Beocord 2000 Beovox 5700 BeoVision 5000 type 3904 BeoVision 4000 type 3901 I’m in touch with a hard core collector of the Beogram as well as B&O themselves… but any input on the price level is highly appreciate.
