Andersley closed its doors last year. The NTTX cars he made are rare to fine anymore. Alan was in the process of selling the HO scale line (molds, ect), but as far as I can remember it was out of my "pre-approved" range for a business loan through my bank. I never did ask if he found a buyer, though he said he'd tell us all on the website. My only conclusion can be he found a buyer, and told everyone, and now the site registration has lapsed.
Edit, or Alan just closed the site, it came up as 403 forbidden for me.
