I'm picking that 40th gear is going to go up in price now that its been discontinued. All the 40th gear that was popular in our youth commands a good price too.
Yup the weekend Modellersloft discontinued the stuff it almost all disappeared from Ebay and it has now started to reappear at really high prices. There are only about half a dozen sets that I would still like to get and am expecting to have to spend a fair whack to get them. There is a company in the US called Cotswolds that have them at not too over inflated prices but shipping will be a bugger.
When confronted by a difficult problem you can solve it more easily by reducing it to the question. How would the Lone Ranger handle this?
