As you may be aware my friend Phil has taken over the wagon bits and kits side of Colin Criag’s useful range and set up Stenson models. Its hoped this will grant Colin more time to develop stuff as well as new things Phil wants to develop himself. 
One of the new bits is this rather handy etch for the HEA steps. Phil has used some good thinking in the design ensuring that the end result has a neat and robust way of actually attaching to the wagon (some purveyors of etched bits take note). The same steps were found on the MEA and MFA wagons too. One down 17 to go!
