I'm always cruising Ebay for interesting stuff, and I when I find something really good, I like to let you know about it.
Amsterdam-based Ebay seller voossie03 offers this fantastic Meccano Sheba and Meccano Magician.
According to the Meccano Wikipedia page, Meccano was founded in England in 1901 by Frank Hornby (who also founded Dinky Toys).
The Ebay listing says that the Sheba model was built as a display to introduce the yellow/blue edition of Meccano and that the Magician model was built as a display for Dinky Toys; ("When the arm with cover is lifted an antique Dinky Toy car is displayed, four different car models possible.")
The current Ebay "Buy it Now" price for the Sheba is $1200 US and the Magician is $ 1300 US. Here are more pictures:
