Bausch & lomb scope info needed

[z2013]

I have a 6 x24 elite 4000 with front AO that came on a rifle I bought. It has the even numbers on elevation knob with hash marks for the odd numbers. There is only two clicks between the numbers and hash marks, so is that half minute clicks?

I have an older Balvar which preceeded the 4000, a 4000 and a 4200 all in 6-24. Haven't resighted any of them in recently and my memory sucks. With all that being said IIRC they are 1/8moa per click? Don't think I have a manual for none as I bought them all used at least 8yrs ago.
