Bosch Magneto Veteran Era

I created a web page about my 1914 Triumph see 1914 Triumph and in the process of learning about it have been on a steep learning curve.
As I find things out I tend to share then via the web so that others have access to them also.

I thought that just a few people would visit this page about magneto's but in the last year over 140,000 people have visited it and downloaded the manuals and literature and this volume (over 600GB) has started to cost me a noticeable charge from my hosting provider. I want to continue to add content to the pages but now need your help to do so.
So if you find something useful or download a manual - please can you donate something even just £1 to help cover the costs.
You can make your donation below via secure Paypal or use a card - Your help is much appreciated.

This page is about Bosch magneto's. Robert Bosch's Magneto transformed motoring as his magneto allowed the creation of a reliable spark.
Some of the information on this page has been very kindly provided by Bosch directly themselves. If it is then you will find (B) to indicate the source.

Below is a list of models produced and when.

Bosch Magneto models

To help you date your Bosch Magneto - the serial numbers by year are below.

Bosch Magneto Production Serial numbers

To help you understand the specification, the information below may help.

Bosch Magneto Specifications

To clarify matters even further I have been able to get access to information kindly provided by the Bosch Historical archive and this lists the different magneto types and when they first came to production. (B)

The advert below would seem to counter the above table as it seems to imply that the DA arrived in 1911.

As the inside of a magneto is a mystery to most of us, I have included below some lovely colour drawings of an early (1902 onwards) Bosch DA2 magneto.

I have added a few pictures below of a Bosch ZE1 magneto that I have bought as a spare and hope to get tested/renovated in the coming months. The serial shows that it was made in 1915.

If you have any manuals for Magneto's of the Veteran era then I would really appreciate a copy so that I can add it to this page. Also please do add any links to this page as it will help others find this information. My email is paulg@go-faster.com

I believe the Bosch ZE1 was fitted to Triumphs from 1912 to 1914. I think the Bosch DA2 was fitted to Triumphs 1906 to 1909 - anyone know any more? I get this from the 1914 Triumph Repair Catalogue, see http://www.go-faster.com/1914TriumphRepairPartsManual.html

How to set the timing on a Bosch Magneto

The following will be useful to anyone trying to set the timing on a ZE1 and probably a useful guide for other models and makes. It comes from a 1914 Triumph publication.

This is the end of the Bosch literature that I have gathered so far.

I have been asked what happened to the supply of magnetos during the First War as at that time Bosch were the main global supplier. I have found the following article which explains matters.

I have managed to find a few old movies from Pioneer Runs from long ago.

In 1955 Gordon Little organised a Pioneer Run to Paris - all 160 miles! if it, you can see a short video here:

I have also managed to find a movie of the 1961 Pioneer run and that is here:
