Family photo with Scootacar

This is a family snapshot probably taken in Scotland, and shows a man with his son and grandson standing next to a small car, possibly a Scootacar.

The Scootacar was a small British microcar that was made between about 1957 and 1964 and has a similarity to the car shown in the photo, but I’m not certain. If there are any car experts who see this post, please give me your opinion.
