Voltages /wiring look good. Give her a try! As Mike posted most of the battery (TRF) sets are very similar. The diagram he posted has resistors in series with the grids of the RF tubes. This is done to stop any oscillation. Atwater Kent used this system. Others like Silvertone (King) used a neutralization condenser (small condenser between grid and plate pins of each RF tube). Other that and the number of tubes there all pretty close.
