Hello Tony

I have been using this for a long time as a basic reference for many of the more common vintage motors. It sets things out pretty clearly and shows which motors are endbell driven are can driven which can be useful.

This is also helpful, particularly for anyone new to vintage motors

The links look the same but they do link to two different webpages. Lots of other interesting stuff on the site about scratchbuilts from the golden age of slotcar racing as well.
