Operational Cushion Type S Scale Draft Gear Box

Operational Cushion Type

S Scale Draft Gear Box

(For Sergent Engineering Couplers)

.

Where there is a need, there should be a model or detail part to fill it.  And while comparing my S-Helper Service
cabooses to prototype photos, I found this need.

Prototype Photos

           

 

No resemblance.

.

Note how far the coupler and draft gear extend out past the walk decks of this caboose in the prototype
photos?  The model's couplers nor it's gear boxes are extended.  I wanted to achieve this look and to
offer both a working an non-working version of the draft gear.

Below is the concept for the operational version.
