I just went hunting for John Lions' book about V6 UNIX.  It is 9099 lines.
(If you don't know about John Lions', you are clearly not an old timer; ask one.)

On the other hand, V7 is considerably bigger than V6, and V6 has few comments.

However, MINIX does not have all the functionality of V7.

Conclusion: probably none, but I don't think the sizes of V7 and MINIX
differ that much.  They do roughly the same thing with the same level of
checking.  It would be surprising if they were that different in size.
