I am looking for a track gage for spacing double track. There used to be a flat grey plastic item with grooves in it. It laid over the rails. The first track was nailed down and you could secure a second track along side with the gage. I have an old one from the HO days but can't find them now in N Scale. I don't even know who made them. --Any ideas?
