Great photos, thanks Howie.
I was looking at the photo of P/1007 and its front clip appears odd, with a slightly higher than standard raised area above the front tires and also seems to sort of raise up higher in the front than standard. If you compare the nose of P/1006, with P/1007 the differance is obvious.
It looks like P/1022, P/1025 and P/1055 also have this same sort of MKI-MKII hybrid noise.
