Just getting back to this thread.
Thanks folks for all of the postings on "Big Ben" and for the sleuthing. Mine is all tan and has a "Best if used by" date of 9/30/2014.
This is another piece that I spent some time looking for on ebay because I saw it in someone's photos of their layout. I have had it for several years now.
And a size comparison with Big Ben
The next layout will have a Wide Gauge portion (maybe 5 rail track) and I have been considering having a World's Fair theme park on it. Perfect place for these pieces, and I also have a reproduction Hellgate Bridge that I could use. Does anyone have a "tinplate" model of any other iconic buildings? Hmmmm wonder if I could find a cookie tin of St Basil's in Moscow.
Thanks again for your posts.
