HO Brass - OMI 6120.1 Seaboard Air Line Centipede #4500 Citrus Scheme
How about something simply gorgeous. This is the Seaboard Air Line DR-12-8-1500/2 otherwise known as the "Centipede". #4500 is a unique example of these engines featuring a slightly modified carbody. Notice the prow over the cab.
This model produced by OMI in 1996 is not only unique due to the fact there was only one road number of this version, but it comes in an OMI black box. Normally the black box is associated with OMI's nicest models. A small handful of models were produced like this. Notice inside the cab, you can read the "Fire Extinguisher" signage. The control stand is painted too!
