LE No.4 - Latest Acquisition

[lawrence_n]

Picked this up recently at a pretty fair price. It looks to be a refurb of some sort but there are some questions about it. The bolt (#3 head) is scrubbed so no serial number. I can't find any FTR markings under the suncorite. Which manufacturer used the "C" in the serial numbering? The date of 1942 is stamped above the serial number. I believe the "star" stamp on the knoxform denotes a rusty barrel, or do I have that wrong?
It has a very nice 5 groove bore that has no pitting but was pretty filthy before I got to work on it. It also has a nice walnut stock though I'd bet it wasn't original to the rifle. So, look at the pics and any input or observations are more than welcome.
