Looking at the IFT from underneath there is a bakelite piece projecting down under the chassis and the pins are anchored onto this. Two stick out one side, two or three the other. The pins are paired up one side and the other. One pair one side primary, one pair the other side secondary. On the second IFT between the UF41 and the UBC41 the secondary is tapped in what seems to be the middle of the winding. This pin is the centre pin of where there are three in a row, but the tapping comes out on the other side of the bakelite bit from the pair of pins which are the ends of the secondary. In other words the centre tap of the secondary lies between the pins for the connections to the primary. Why? Makes for an easier layout under chassis. Confusing much?
