Coupler Assembly 1 inch scale

This is a complete coupler with knuckle and pins in one piece.  It represents a late 19th-early 20th century  coupler with slot and pin hole in the knuckle for mating with link-and-pin couplings.  It is based on MCB designs of that period.

The shank is 2" long by 1/2" square cross-section with plain end containing no holes or details at the outer end.  This allows adaptation to a variety of applications.
