Thank you very much !
I didn't knew that we can order the car with two roof style
I think that Neil has already advised you that the first car is the standard model with the normal 'easy-up' hood. The last three photos show cars with the reduced height screen and the traditional style hood with 11-studs, as fitted by Morgan Hamburg.
My car has the Morgan Hamburg lowered screen and an 11-stud hood developed by MMC for my car, you can see we did a different rear screen treatment and TBH it also fits much better and so far, does not leak!
'Scuse the quality of the photos, but they are all I've uploaded to Photobucket so far.
Regarding the roll bar, MMC have developed and fitted a single roll bar that fits under my hood, so I guess would easily fit under an 'easy-up' hood, but I have not taken any photos of this as yet. It is different to the Speedster roll-hoops as it is one hoop that is the width of the car and thus does not compromise the storage space behind the seats. MMC now have this design on CAD/CAM so can replicate it if anyone so desires.
Lastly, let me say that the lowered screen and hood and the roll-bar are all bespoke items and not a separate model, and thus MMC can fit them to your car but be prepared for quite a bit extra
