Hello Ian,
Yes that was the excellent book and I think possibly there was a later version of it.

Re the slugs etc, normally if if not already been got, they do not need re alignment.

I have done many restorations of valve equipment and very few have warranted alignment.

I could only suggest if needed any adjustment on the trimmers, possibly paint remover or nail polish remover might be worth a try.

Regards,

David
