Hold on - that is not an IF transformer. It looks like an antenna coil.

Please study the under-chassis drawing (taken from Service Bulletin 114, for model 51) carefully.

Notice that the 2nd IF transformer, part (16), is in a cylindrical container mounted above the 2nd det. tube socket (when looking underneath the chassis). The 1st IF transformer, part (12), is in an identical cylindrical metal container, mounted above the 1st det.-osc. tube socket. The antenna coil, part (2) and probably the coil you have photographed, is mounted inside the chassis as shown in the drawing below.

Please confirm where that coil came from in the chassis.
