Since my posting I have been informed the site originally recommended is not entirely correct and would suggest this one below.
The site ;-
www.wolfbane. com/vreg. htm does in fact show London as 1st Registered place for 'MXF 682' and confirms my initial belief.
Sorry for passing duff info. on, just shows how easily we can be drawn in to spread errors.
Have informed my original source of his error and suggested the better site above would be more appropriate.
Regards
Michael
