bushnell 75-4124-o AC?

[nelson34]

i have a bushnell scope i'm trying to get some info on. it appears to be an older scope and i am coming up w/ nothing on a google search. (might just be typing it in wrong) but it is a 4-12x40 w/ adjustable objective and a target turret w/ 150 to 500 on it. it has what looks like a ranging reticle similar to the older redfields but it is in the middle of the reticle instead of the top. and on the magnification ring it has the magnification and then three sets of numbers in different colors w/ some letters. i will try to post some pics in the morn once i get the camera going.

any info would be appreciated. thanks
