I want to make a 'cat ladder' for my 7mm narrow gauge layout. On Peco's website they advertise LK-748 ladders, as etched brass. Great, solder some brass loops on the sides, add a couple of strips of brass rod top to bottom, half an hours work, and hey presto one 'cat ladder'. Ordered said LK-748 (not from peco) when it arrived it was plastic. As most people know it is a bit difficult to solder brass loops to plastic.
So far I have emailed Peco three times, as to why they are plastic and not etched brass as advertised, with no response. Not very good for a so called 'top' model railway company
