Hey all, I've been looking for an M1icon Carbine twice a day for almost a year now, and my search finally came to a close. I have a lot of detail below, but I'm kind of confused with the fact that it's a S'G' (Grand Rapids?) but in the 357 serial range. I have attached a bunch of pictures that I took after I ripped it apart when I got home and it actually looks like it has a ton of S'G' parts, which I was not expecting. I'm still kind of ignorant on carbines so I'm hoping to get some help on some questions. Thanks in advance!!!

1) Does anyone have an answer for the serial/S'G' discrepancy?
2) Does anyone have recommendations on who can repair the guide lug on my slide? I think it's too worn as it popped out on me after I put it back together. I have an image in the link below if you'd like to see the lug.
3) Is S'G' technically more rare than a Rock-Ola? I was really trying to hunt down a Standard Product being from Northern Ohio, but this one just spoke to me...
4) What does the V on the left side of my receiver mean?
5) Does the IU magazine that looks brand new and is blued sound right?
