Nothing wrong with your work at all. We have to remember that the set could well have been in use for twenty or more years, so if a part failed like the mains transformer then a substitute would have been fitted. My wartime utility set was in regular use up to 2003 when it's owner passed away, it's now on display at my friends museum.
One small point is your isolation tx, a single secondary winding and one diode will be half wave rectification, so smoothing may need to be increased, you could use a bridge rectifier but remember to add in a limiter resistor so the HT is correct when the set is warmed up.
