I guess you mean IF transformer? No RF xfmrs in that set.
The first IF is pretty generic. Note that the second one has the 'scrubber' components (R6+ two caps) mounted inside the xfmr. That's common too in 1950s sets but note that it is not your standard 4 connection can.
You can mount the R6 and two disc caps (100-150pf) externally if need be.
Otherwise, don't be concerned over the DC resistance of the coils. That has no impact on the circuit. If your replacement is of the same general type from that era you can pretty much count on it being the same frequency (455kc).
