Bringing to mind Jim Hensons lovable creation, the model has gone on to earn itself the nickname 'Kermit'. Early Kermits are recognisable by their 'Flat 4' bezels. This refers to the execution of the 40 on the green insert whereby the 4 has a flat top in comparison with 4s that can be found on later iterations which have a pointed top to the 4.
