Thanks Andy, I agree, the potential range is too niche and people would not buy it in enough numbers to make a profit, what we as collectors sometimes forget is that to manufaturers this is a business and ranges have to sell and make a profit. All of us collectors have our own 'pet' era, vehicle, battle, etc. Just start a threat on what new range etc people would like to see and options come flooding in. Any new range takes resources and time which could be used on increasing to current ranges [K & C do a lot of different ranges], as Andy says, and people would complaint if there was not a Tiger 1 released every 4 months [that is a joke]. They have to make what sells, if not they go out of business, the amount of money it costs as well to develop a new range must be high, higher than many of us think.
I am thankful for what K & C and other manufacturers produce and keep me collecting, a female relative of mine calls my collection 'man ornaments' or 'man nic naks'.
