Had a little bit of insomnia, so I did the logical thing and looked for photos of AC Ace cars! Stumbled onto these with their interesting steering wheels. The red one is a early model AC engine powered car, the blue one, looks like an late Bristol engine car, with glove box lid and the bend on the gear shift. Now, I am very curious about these steering wheels. When were they added, 1950s, 60s, or latter? Were they a popular add on in that period? I don't know, but would love to Know!
