I bought my 1965 Tiger from Germany as well. It is a RRO car. RHD for export, some how it ended up in Germany, first registered there in 1966. It had the original specification plate as well as the German plate. The chassis number stamped to the firewall. Tiger scipts on each guard and Alpine 260 badges elswhere. Also on the specification plate it has Alpine-206-V8- 1,224,888.
Looks as though you spec plate has been removed.
