What is the difference between a Constantmesh and Synchromesh Gearbox?

The difference between getting your HR (Heavy Rigid) Licence in a synchromesh gearbox or a constantmesh is that the Heavy Rigid licence will be issued with a condition-b because your heavy vehicle training and assessment has been carried out in a vehicle with a synchromesh transmission (or gearbox). The condition - B (restriction) is also applied to training conducted in a heavy rigid truck with automatic gearbox.
