I just stumbled across this site and a quick search on this forum didn't find any mention of it, so forgive me if it has been discussed before or you already know about it.

They have for download old Lucas part catalogueson lights, switches and workshop manuals on magnetos.

May be of some value for people

That is an excellent website, in addition to all the great free information, they manufacture a replacement capacitor that is relocated to the points area where you can actually get to the condenser, rather than have it buried inside the armature as the original was. I rebuild Lucas & BTH magnetos near Cleveland Ohio & it is the ONLY capacitor I will put in a magneto. They have an excellent one for the MO1 Magdyno!
If anyone here needs one of these capacitors , new or used magneto parts, or wants work done on there magnetos, feel free to email me sbrolund@yahoo.com

Thank you !

Hey Skip,

A friend of mine has 8-9 of the magdynos needing rebuilding. Problem is, they are in Pakistan. But, if they show up, care for a job on them?

He is a trustworthy man, and I have no money in them until they arrive.

Tony, THANK YOU!!!

I'm in Grand Rapids, MI so we are close.
