I took down one of these guns today, cleaned it and put it back together. I was able to find a photo of an instruction manual. I've moved a copy to my website as I'm not sure how to include files here. It can be found here: http://themdg.org/pics/posts/win270instr.jpg
Feel free to contact me if that link doesn't work someday.
Just in case, I've transcribed the take down and assembly portions below.
Some tips:
Text below is transcribed from the Winchester 270 instruction manual, linked above.
