thanx for the answers-it clears things up on what it is. the numbers on the bees sheet are 1834 which would be 18th hour 34th minute correct? i`m now noticing four digit numbers on some 70 and 71 sheets i`ve got pics of at the very bottom, would this be the same thing?

another question on the bees sheet - what are the numbers on the bottom? it says 05 AUTOMATIC 6 PAK
what is the 05 for? anyone with a 69 1/2 bee build sheet with something written on the bottom?
all the best
frank.
