Thanks David, great input. This was one of those "I want to call Arno" moments when I saw it. I am pretty sure this was originally sold in kit form due to a baggie of screws and nuts in the box along with the unused stickers and brass wire.
Did a little looking around and Gargraves track would have made sense at that time. Most Std Gauge tubular track is 14", not 12" as in the flyer. Gargraves is sectional is actually 12.4". Also, the transformer has the appearance and specs to have been a MRC 500 series. Still a lot to learn, but I know more than I did yesterday.
