Thanks Neil,
It would appear that all of these tools including what I described as a Flavia hub tool are in fact multi purpose Lancia tools not necessarily relevant to just one model or application.
Aurelia transaxles for example have several examples where I have always used a C spanner (or worse) so I have decided to keep all of these and make sure they are more accessible.
Simon Ingman has a book with details of a lot of Lancia special tools in it ( it has all the above for example) and this book doesn't seem to particularly mention specific Models, just general applications.
