Hi everyone, I know this topic concerning Thomas Smith & Sons has been going for a while now but I have a book in my possession from this company. My partner's grandfather used to work there, the book is called The century of Thomas Smith & Sons and was issued in 1948. It has the name Perfect on the cover, the person to whom it was issued to is Joseph Perrett and it also has the number 38 which may be his works number. Anyone know him.. Thanks
