Weaver scope any info?

[flamoudi]

I have been given a scope to research by a friend and I can't find much about it other than from the US sites.

It's a Weaver CKT15 15x42 MICRO-TRAC with duplex reticule, AO and resettable turrets. Think it could be quite an old model but it looks nice.

Is there any interest in these older scopes and who uses/what disciplines use this type?

He'd sell it if he knew roughly what it's worth, but never seen one for sale over here and could use a bit of help?

I hope I don't get my legs slapped for posting in the wrong place!
