M24 Chaffee Telescopic Sight

Hi all,

I'm trying to find out information concerning a sight I was given and what it may be worth, if anything. Over at another forum, I was told that this sight was for a M24 Chaffee Tank but that's really all I know. It is marked Telescope M71K and has an inverted Christmas tree looking reticule that I believe are marked 8, 16, 32 and 42 at certain intervals. Here are a couple of pics>





Any insight is appreciated.

Thanks,

Paul
