I purchased Model Engineers Handbook by Tubal Cain 3rd edition some 3 yrs ago only ever flipped through it. Last night I dragged it off the shelf to do some ground work on electrics which is section 12 of the book.
No section 12 not even section 11 or 13 I thought I was going
bonkers as all I kept seeing was section 8, 9 & 10 yep they had bound the book with double those sections left out 11, 12 & 13.
Waiting to hear from the supplier here in Victoria.
