It's very common to see an Austin Sevens with its hood down, but with the frame sticks poking untidily into the air. On early cars where the hood frame rested on its pair of body supports, clips were fitted that held the frame together. Well, this was almost the case, as the clips were hard to operate, not particularly robust, and easily bent out of shape, becoming ineffective and so unused. A simple solution was to use a pair of dog collar straps around the frame, which did tidy things up.
By September, 1929, Austin realised that a better solution was needed, and arranged for the now very much more substantial hood to have its frame rest on rubber blocks fitted to more robust support brackets Towards the front of each of the hood's two, flat-steel side frames was riveted a leather strap (shown below), the free end of which was equipped with a lift-the-dot fastener. With the hood down, the strap went over the hood irons and was clipped over the stud that protruded from the hood support bracket. By this means, the hood sticks were held together rather more firmly than before; even so, many owners still regarded this as inadequate and added the dog collar straps as well.
The hood-rail-mounted leather straps are easy enough to source, and the rubber blocks can be made from the rubber bench blocks used by jewellers for working on small parts; to find them, Google "jewellers rubber bench blocks".
If your car has a hood bag, it can also be secured at the front ears using the rubber blocks' lift-a-dot studs, though these will need to be the double-length type. The writer found that while making those for his car, the threaded section of the stud needed to be made much longer, a simple job that involved cutting off the original, tapping the hole 2BA and Loctiting in a suitable length of 2BA studding. You'll also have to make, drill and tap a small  metal plate to fit against the back of the rubber block.
