The scale below is very much a personal one based on my perception of the availability of various Hornby Dublo 2-Rail items for sale at UK toyfairs, swapmeets, auctions, and Ebay sales, that are in excellent to mint condition. An item may be common, but its box (or other item of packing) may be rare, and vice versa. In general, the less common the item, the rarer it is to find the same object in excellent to mint condition. There is no attempt on this web site to put a value on any object.
