Peter,
Hope the link to the ebay listing works as the photographs should answer your question.
These are the starter motors I have bought from this supplier and fitted to my two 401's, I have in fact just bought another to keep in the spares store.
They are made by ISKRA Type no AZF1508 model no 11130174 they cross referenced to the Lucas number in the BODA bulletin which from memory was an LRS293.
Geoff.
