Without equal

Came across this Matchless 500 single in Olbia airport, being used as an eye catcher for an expensive men's clothing retailer.  I owned a 350 cc version of this in the early '60s,. before becoming a Mod!  It's reg was MSR180, and it was traded in against a new Lambretta Li150, DWS17C
(Can't recall the reg of the Vespa previously mentioned elsewhere.)
PS: This Matchless has an Inverness registration, HSK586.
