Might start here:
http://www.winchestercollector.org/I remember when you posted the pics of the rifle. Can't recall commenting on it so here goes.
Have you taken the barreled action out of the stock? Reason I ask is because the mag box would be different than say a .270. I can't recall the stamp on the box itself but I know it has a letter on it.
If the barrel was original to another rifle and set back, the taper would probably be altered and the fit of the stock would likely have to be changed or at the very least have unsightly gaps which it does not appear to have. Any changes to the barrel channel? Look like a factory finish?
How long is the barrel from the bolt face? Standard length or some oddball number? If oddball you might convert to metric which is how the European rifles are listed for sale overseas. A 60cm barrel would equal 23.6".
