Best left overnight. Diff oil is quite thick and treacly so takes a while to fully drain out. Same after you've filled - let the excess drain back out. Too much oil just causes problems at the hubs with it getting past the seals & onto the brakes.
If you can see into the level hole, rotate the axle so that you can inject the oil past the crown wheel. It saves a bit of mopping up...
On the subject of your gearbox, if the car is a 1933 model it should be fitted with a four speed crash box. This is easily identified by the presence of a large forward facing nut on the gearbox top casting, ahead of the gear lever. Later cars, (without the nut on the casing) will have a synchro box, either on 3rd and 4th or 2nd, 3rd & 4th.
However, the 4 speed crash box is very cleverly made, robust and pretty reliable, if a bit slow to operate by the double de-clutch method. Forget 1st gear - most of the time you can just set off in 2nd. It only featured in 1933 model cars.
