Having reached "a certain age" I decided not to retire or sell the business but to "semi-retire" . Do less shows etc myself, allow some others to sell these at shows and concentrate on mail order. This means the kits will still be available to those who want them but I will be working for a lot fewer hours.  Changes in how they are produced will mean a slight increase in prices, probably in the new year. With some types I am working out of a finite stock of mouldings.  Up till now I have been happy to sell individual mouldings but as stocks run down I would rather keep these for complete kits. There are a lot of unbuilt but opened kits coming onto the second hand market. Should you consider buying these take care to make sure they really are complete as I might not be able to supply any missing parts
