...Should have guessed the seller was the German cousin of the Freddy Krueger outfit we have here ; https://www.ebay.co.uk/sch/mjtronix/m.html David
In all honesty, I wish we had vendors near me who offered those kinds of "grab bags" of run-end components... back in the day we had a local Surplus Outlet that did 1 lb, 5 lb and 10 lb "junk boxes"; I got a USAF-labeled gyroscope in one and 50 pieces of xenon strobe PCB in another... and more random resistors, switches, pots caps & semis than I could be arsed to count in every box...

They aren't run-end parts, it's almost all pulls from old test equipment & military gear, I wonder how they manage to desolder all those parts in a quick enough way to make it worthwhile doing.

Hot air gun and bang the board on the bench is a common technique
Personally I don't like the seller. He seems to be breaking kit for precious metals and selling what he does not want. Prices are high and parts are often misrepresented. Typical of ebay his over-priced stuff often sells. He has listed HP 8922x cellphone test set modules as having been removed from a 8920A. The modules are similar, but most are not identical and won't work properly in a 8920x
He may be De-milling some kit that he can't contractually sell complete but he has also bought TE items from RAMCO auctions and broken then. Unfortunatly a lot of kit sells for less than you can get for its component parts.
