2015 Rush -> RMK

[mountainhorse]

The RMK and PRO-RMK 60th Anniversary editions have red painted spindles.
The "Terrain Dominators" have black painted spindles.

The terrain domination editions have black spindles and the 60th anniversary edition has red spindles, but I think you have to get the actual 60th edition model, not just the le with 60th anniversary graphics, but I could be wrong on that

Edit: Whoops, beat me to it I see

Probably the same crappy chipping paint the rails have.
