ST70 Headlight Control Switch

Hi All,
Just in the process of (trying) to resurrect an ST70. It has a few bits missing, particularly the Head Light Control switch. Anyone got one for sale or could you suggest where I could get one?
Cheers

Have you tried David Silver Spares Ltd .?

Hi Buddy.
Yes tried David Silvers and Shire Bikes. Even tried Honda direct! No luck.
The wiring diagram I am looking at has 7 wires on the Headlight control switch. I know that some have 5. My bike is a 1977 UK bike. I have been told two different part numbers; 35150-098-620 and 35150-098-630. I am getting conflicting information, one says I need the "630"! and Others say a "620" will fit. Any suggestions would be appreciated.
There is one on EvilBay for £250! WTF
Cheers
