I just caught up on these posts (been at York for 5 days, returned last night) thank you for all of the comments, pics and catalog images.
Looks like my train is getting newer and newer - I was told 1912 when I bought it, then I thought 1922-25 and now, from the 1930 catalog pic pf a German market version, it might be from that year.
Dorfanman, I tried to find you in the Yellow hall but could not - the table charts made no sense to me (they seemed backward) and the hall captain/monitor had no clue.
I would be great if someone comes up with a set of instructions for a set with this bulb transformer ns/or somesort of catalog pic of my American market set..
