Hoping to get some help from the group in determining the year for an AC IB serial number IB3040. I have looked at several websites and am stuck between it being a 1953 or 1954. Looks to me like it was built late in 1953 but wanted to see if anyone could tell me for sure.

Thank you Steve! That was my assumption as well. It was produced late in 1953. Thank you for confirming.
