The Typhoon came with both a car door (early) and bubble canopy (later). The bubble canopy you have doesn't look right. Google Hawker Typhoon and you'll see that the one you have there looks too big.
As for the markings, it doesn't look like the previous owner went for authenticity. The colours aren't correct for a desert scheme nor is the pattern, The wing roundels look small and the fin flash also looks small. I bet you the guy's initials were TGY.
And yes, you need a spinner and no it's not the same as a Spitfire.
