This thread has been hijacked by some overly precious armchair pilots. There a number of replica aircraft out there which use the original name. Mustang, FW190 to name two. There are also other aircraft with the name but no resemblance to the original. Mustang again, Texan etc.
It's easy to sit back and criticise but when these armchair experts get up off their backsides and buy a genuine Spitfire they will have paid for the right to complain. I'm sure that if given the chance to fly a MK 25/26 they wouldn't knock it back because of the name.
It reminds me of the story, real or not, when two enthusiasts were at an airshow and criticising the paint scheme detail on a warbird when a someone nearby (the owner) turned and asked them "what colour is yours?"
Meanwhile the MK25/26 owners are having more fun than you can poke a stick at.
