That roll over hoop looks like a Librands unit http://www.librands.co.uk/products/rollbar.htm

However you need to note the following for real track work and saftey.

According to the MSA Regulations (blue book)

The roll bar should be sufficently high that in the event of the vehicle turning up side down the drivers head with a helmet on does not protrude above a virtual line between the highest structural point at the front of the car (on a Morgan you could believe this is the top of the cowel... although could better assume the top of the cross frame.) and the top of the roll-bar.

Clearly with this particular roll-bar as can be seen from the pictures even the drivers head with no helmet protrudes above this line and therefore should be considered cosmetic only.

Unfortunately, one symptom this tends to induce in Morgans, is that unless very creative most true safety roll-bars restrict the ability to raise and lower the roof.... and even then to get the helmet height low enough the seats need to be lowered and rake adjusted... usually resulting in an after-market seat such as Sparco Rev or a Tillet type..... The Roadster Lightweight for example has this set-up to meet regs.
