Asi superscope 4-12x40 ao info

[Nickos]

Hi guys does anyone one have any info on these scopes, age and value(condition very good)
google draws a blank!
It's a 4-12x40 with ao
It's got a normal crosshair with an additional horizontal line above the 1st.
And numbers on the top turret marked 'trc2'150-500
The adjustable mag on the rear also has D E A with varying numbers.
Thankyou

I am guessing the numbers are indications that it is designed to act as BDC at those ranges in yards. The dea and extra line may be some form of range finding by quarry size. I suspect it is a deer stalking optic. I have been known to occasionally be wrong though :-)
