Interestingly that both my concise 28N and 46 don’t have these integer conversions on them! Need a little more detective work here.

It's interesting to compare the Concise table of conversions with that found on the circular slide rules made by Blundell Rules Ltd. (BRL) in the late 1950s/early 1960s - as far as I can tell, they are identical in every respect. I've uploaded
a file showing two different variants (blundell_academy310+s140.jpg)
