I didn't fancy butchering the loom or re-soldering connections when it came to replacing the ignition switch on Binny (early 4 pin potted connector) but struggled to find the right early part (216864 Ignition Switch 1850 to WF26607 )
As a last ditch I dropped Mick Dolphin an email and lo-and-behold he has them in stock!
I enquired on Thursday, paid on Friday and the parts arrived this morning - great parts and great service!
He might not have a fancy website, but well worth trying if you are looking for hard to find parts: http://www.mickdolphin.co.uk/frontpage.htm

Support your smaller Triumph/Classic suppliers! (I'm a fan of Paddocks, Fitchetts, Canleys, Robsport etc.)
