I just got off the phone with the Winchester customer service people, I had them look up the specs my new 45-70.
I gave them the serial number, barrel length etc., it is a 20 inch carbine with a full mag.
Apparently this little carbine is quite a rare piece, it's one of only 350 made for a limited run in 2012 for the Vegas Shotshow.
No wonder a local 45-70 enthusiast was so eager to try a trade with me, I'm glad I found out more info before possibly trading it off.
They are listed for $1350 US before taxes, so that's about $20,000 Canadian now that our dollar sucks so hard.
