OIT - Scammell mechanical horse (1-148)

Trying to model the origin of containerization in n-scale, I’m of course liked to have a model of the famous Scammell mechanical horse and/or the Scarab:

There are fine models available for both from Oxford-Diecast:

unfortunately the trailer doesn’t fit to containers available from PECO or Graham Farish (it’s a little to short), so I created my own trailer for them.

In the next step I used the fine model of timbologist:

and adapted it to n-scale, fitting connections to my trailer.

I gave special attention to the famous and for its time very progressive Scammell-coupling:

So there is a version of the mechanical horse already with the coupling – this is made, in case you like to show the horse/trailer on road only – and there is a version without the coupling. The coupling can be mounted below the trailer and there is a version of the coupling, to be clipped on the mechanical horse. So with the “MechHorse_alone”, a trailer and the both version of “fore_wheels” (coupling) you would have maximum flexibility for your scene.

At the end there is also a driver for the mechanical horse.

For windows I used Micro Kristal Klear:

but then the driver becomes hardly visible.

All models sized for British n-scale (1:148).
