hi,
no, have not detected the sell,
It was obviously the septembre watch from Ricardo.de http://www.ricardo.ch/kaufen/uhren-und-schmuck/markenuhren/tag-heuer/tag-heuer-monaco-1974-schwarz/v/an743069154/
;-) Swiss people from Thun near Zürich give it to a swiss auctioneer,.....

...those were the days , have seen 2 on ebay in the years..... :-)
and this on ricardo, ......remember Amer told us he have had contact to the people.
cheers mich
