hey guys

just got it in from monarch today, but im confused. I put my stepping into google and what it pulled up was another guys thread here about the same stepping, and it said it was a newcastle. i thought that when I bought this 3500+ from monarch it would def be a winchester. lol was I wrong? where can I for sure buy a 3500+ winnie for ~$270?

heres what it says on the core:
ADA3500DEP4AW
CBAXC 0437SPBW
