Thanks to all for your help...

I am curious as to why some of you might consider this to be a 'lunch-box special' as opposed to a made up piece, say from the '50s or '60s. What guides one to this evaluation? I can't determine whether there is a C/N on the left side of the front toggle or the back toggle, which one would assume if it had the other C/Ns, then I would think that one should appear there as well. Also, looking at the front of the receiver, there appears to be a '6', which has been ground off, partly obscured by the '0'. Also, would a factory replacement barrel not have the bore measurements?
With my limited knowledge, I would look at this to be a highly fiddled with piece.
I am just trying to figure out how one would tell the difference in a factory job, versus a later gunsmith rework? Would appreciate any info available.
Thanks, barr

FWIW... There is hardly any bevel left on the top of the foward toggle, which indicates to me that the manufacturer's mark was ground off.
