Hello Edgar,
Good to here from you. You certainly seem to have good luck in picking up presentable machines from dating from @ 1970 onwards....your finds always bring back memories for me !!
I bought a brand new GS80 with extras in Feb 92...I think I bought it at the best time, although it was the best part of £300, as nilfisk began to deviate from their classic design in machines and tools.
I have a volta 201 type and is 650 watts and probably the best design of the 70's; not many voltas over here ?
The electrolux cylinder is obviously the european version of UK LUTON built late 87 (@ 1976-79) 550 watts; UK entry level model (my first 'new' cleaner) @ £18.....a great little vac probably the best lux then offered over here at the time !!
I think I can remember a mustard / green type miele like the one in this thread,available in the UK in the 80's.....very expensive over here.....built like a tank and only available through a limited number of upmarket retailers......nearly £150 was a lot then !!
Regards, Walter, UK.
