This is a set of four Type 28 fixed link couplings designed to fit into NEM sockets on British outline wagons.
Type 28 = Big-Step Up 3 Link coupling giving 19mm between NEM sockets.
Please refer to my website for the different types of couplings available, sample packs with a variety of couplings are available in my shop.
This kit is only printable in the FUD material and will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or a similar non-corrosive product for 24 hours. Then rinsing off with warm water and allowing to dry.
