IBs didn’t get there own sn until 46. Prior to that they were just regular b serial numbers. There are 260 of those units

Robert is right.. If you have an IB with a 5 DIGIT serial number, then it was built in the earlier 1940s and would be on the "B" serial number list..... however i did once see an IB built in 1939. It had no c-channel frame and had hand brakes... Dont remember the serial number of it. ( could have been 3 or 4 digits).

Like them all, but love the "B"s.
