Mitch Klempf of Klempfs British Parts in Minnesota USA has sent in the following spares update:
Here is a link to the left hand side battery side covers that are made of steel, these were made back in the 1970’s
These starter drive rings are NOS from the 1970’s
We have a very good stock of parts for the old vintage British bikes. Check our website:
Another thing the members may be interested in are the “Mitch’s Tips”
I have attached a couple for you to take a look at. They can be viewed and downloaded at our website.
The tip sheets are not exclusive to the Triples, but might be of use for their other British bikes.
