Andy and List,

When?I first saw them at the NMRA National show several months ago, I was also "brown away". However, after experimenting with them for the last two weeks, I have to say there?are some issues. The big issue is their attachment. There is a "pin" that is part of the moulding that I am assuming is for their attachment to the underframe.

...I am yet to paint them to see if they will "hold" paint-I have my doubts.

In closing, these are a far better idea than plastic or brass air hose if we can make them work.
