Class A.
Given that the M420 has became the most common unit on my roster a little variety was necessary. With this in mind 3538 was taken out of service and modified to replicate one of the earlier units from the MR20a class. The last few members of this class share the same style of handrails that were used on later models so that eliminated one job. I did have to fabricate a new longer fuel tank though as well as changing the access door on the engineers side of the cab. On the earlier units this was one large door instead of the two piece style of later units.
