Well I've found a few retailers in the US that still have the Hershey Streetcar in stock but none at all in the UK or anywhere else this side of the Pond so it must have been a very popular model.
Unfortunately the cost of shipping an example of this model to England from the USA or Canada will in most cases double the cost of buying it and in several cases more than treble the cost of buying it which unfortunately makes it an unviable proposition for me as its more than I can sensibly afford to spend.
With any luck one may come up for sale in the preowned market category over here so I will just have to keep a look out for one.
