SCS329M and RAG394M help needed

Hi members.

The requests are coming in thick and fast at the moment. This one is from member Ian Longhorn. Can anyone help?

I have negatives of SCS329M and RAG394M which after service with Northern Scottish migrated to South Wales. The shots I have of them are taken in Cardiff but I am struggling to find the operator. I hope someone can help .
Many thanks

Ian
